Problems with Music Playback on the HD2

Hello!
I have searched now for several hours in different forums and many threads, but I did not find my specific problems or any solutions to them. Therefore I want to start a new thread.
One thing in advance: I have my HD2 now for about 3 weeks and generally I am very happy with it. Unfortunately, I am experiencing some really bothering problems with music playback, and as this is the second most important feature to me (after telephony), I really hope, that there is some solution out there.
1. According to some Internet pages the integrated music player of the HD2 should be capable of gapless playback of MP3 files since a software update. Well, I have installed the latest 1.66.xx ROM for my device, and unfortunately gapless playback does not work at all. When I am listening to a concert and one track ends and another starts, I always hear a small interruption in the applause. When I play back the exact same tracks on my PC with Winamp everything works fine and both tracks play back to back without any interruption at all. As far as I know Winamp prebuffers approx. 2 seconds and in my opinion for gapless playback the integrated music player of the HD2 should too, but obviously does not.
2. Especially when I am listening to tracks with a quite low volume (e.g. instrumental Soundtrack), I always hear a short "crackling" sound at the transition from one track to the next (or at the beginning of the new track). One forum entry claimed, that this "crackling" sound is caused by the fact, that the HD2 disables the headphones output after approx. 2 seconds of silence and just reactivates it again when there is sound again. The reactivation of the headphones output seems to result in the "crackling" sound.
3. I thought that I can get rid of both problems just by using another player software as alternative, I even bought one of these. I tested "Microfi Nitrogen", "MortPlayer", "Slide 2 Play" and "PocketMusic".
Using the "Cross Fade" mode of "PocketMusic" in fact solved the first two problems effectively, so I got gapless playback without a "crackling" sound between two tracks.
Unfortunately, with all of these alternate players I experienced one even more bothering problem: Every now and then (approx. 1 to 2 times per minute of playback) a short "clicking" sound is audible during playback, which reminds of an scratched vinyl disc. If I rewind the track, the "clicking" sound does not occur at the same position, but at another at a later time. These "clicking" sounds do not occur at all with the integrated music player of the HD2, but with ALL of the mentioned alternate music players I tested. Of course, the "clicking" sounds are audible better, when you are listening to instrumental or classic music with a relatively low volume than with loud Rock or Heavy Metal music tracks.
To avoid the obvious suggestions:
- The problems were already present with the 1.48.xx ROM and are still present with the 1.66.xx ROM.
- I tested several different headphones (cheap and expensive ones) including the original HTC ones which shipped with the HD2.
- I can rule out the MP3s as cause of the problems: There are absolutely no problems with them when they are played back on the PC with Winamp, a Sony-Ericsson phone, an iPod or when played back with the mentioned alternate players on Pocket LOOX N110, N120 (Prototype), 420, N500 and N520.
- It does not matter whether the MP3s are located on the internal memory of the HD2 or the SD card.
- I already tried to disable all data connections on the HD2 and closed all other programs using the Task Manager to avoid any interferences.
- I even performed a Hard Reset without installing additional software or tweaks (except for one of the alternate players).
- I tested "PocketMusic" with all possible settings regarding Cache, Buffer Priority etc..
- It does not matter, whether any Equalizer (if available) are enabled or not.
- I also tested my brother's HD2, and both devices - my own HD2 and my brother's HD2 - show the same problems.
My questions now are:
a) Can anybody verify the "clicking" sounds when using an alternate music player software? If not, which music player software do you use at which settings?
b) Is it possible somehow to disable the interruptions between two tracks with the integrated music player of the HD2 and thus enable true gapless MP3 playback, for example by an undocumented registry setting regarding (pre-)buffer size or Caching?
c) Is it possible to disable the deactivation of the Headphones output after some seconds of silence (which is said to cause the "crackling" sound), so that the Headphones output is always enabled when there is playback using the integrated music player of the HD2, for example by a Registry setting?
Generally, I would love to continue using the integrated music player of the HD2 (which I am doing now anyway, and it looks really nice, by the way), but the missing gapless playback and the "crackling" sound during the transition of tracks is really bothering me very much.
Many thanks in advance for your help!

I dont get the crackling sounds you speak of but it is a little off putting when I'm listening to a non stop mix CD thats broken up into tracks, when a track abruptly ends it's followed by a half second silence only to head right back into the music.
Is there some registry tweak that we can use to either eliminate this gap or even shorten it?

I use Coreplayer, and it seems they screwed up the standby keepalive at least on the HD2. With BT headphones, if I start music and then turn the screen off with the power button, I'll start getting random skips. With wired headphones ith completely stops playing music. So I've bound long press windows key to "turn screen off" in AEBPlus, and I now have no more problem with that (when I remember to press that one instead of the power button, that is...). Works perfectly, never heard a skip anymore (I have a set of Sennheiser PX200II, way good enough to make anything noticeable )
Your problems with 3rd-party players could be linked, no idea...

Not sure about the crackling, as I listen to music for at least 2 hours a day on the way to work and I use a pair of Sennheiser HD-25 headphones (http://www.sennheiser.co.uk/uk/home...onal_headphones-headsets_dj-headphones_502188) and I don't hear any crackling between tracks or in periods of silence. Only hear vinyl crackle where the source for the MP3 is vinyl.
The lack of gapless playback, as jmwarren85 mentioned is really annoying as I listen to a lot of mix albums... one solution I use is to take all the MP3's from that disc and splice them into a single track and then listen to that on the HD2.
Also finally I can't say I have heard any clicking noises on my HD2 but I know what sort of clicking you are referring to and that may be due to the encoder used and/or its settings when the MP3's were encoded. Some of the codecs that players use for decoding MP3's aren't the best (ie not well optimised, which can especially be a problem on a mobile device) and you occasionally get audio artifacts.
I use LAME with VBR-0 with quality 0 (highest) and the minimum bit rate of 128 and maximum bit rate of 320 using 44.1kHz instead of 48kHz for compatibility and I don't seem to get any problems.
Hope this helps...

Hi!
Thank you for your messages!
After extensive testing, I have finally bought "Pocket Player" which has solved all of my problems.
But I still think, that the integrated player (which at least looks great) has some bugs in the audio department that should be fixed.

Hello there.
The crackling you've described may be in relation to network use, for example every time my phone uses the 'net connection (HSDPA) to get weather, location or email, the audio stops for a brief second and continues; this is almost like the crackle you describe.
This in turn disables the graphic equalizer, so I am regularly re-enabling this between songs or in the middle of songs.
Test the theory by putting your phone in airplane mode or disabling all data reliant services to see if this is the issue. Even if it is I can't offer a fix, but at least you know what the issue is at least with the built in HD2 audio app.

I have the exact same issues as the OP. I contacted HTC about the gapless playback and they said they're testing...
I hear a soft/small pop between tracks too when I'm using headphones.
I also sometimes experience another issue where sometimes instead of going to the next song after finishing the current one, it just stops. Time remaining shows 0 secs, it's 'playing' (pause button is shown) but it doesn't move on.

I know it's a little late to reply to this post, but it was just to say that you can remove the gaps between the tracks using Ogg Vorbis encoding instead of MP3 encoding. Winamp for Android can read ogg tracks
About sound quality, there is always a quiet background interferences noise that bothers me. It is particularly annoying when listening quiet music (OST, classical...)

Really strange phono audio problem

Hi guys, I have noticed that the DHD has some issues with audio playing. I have noticed that sometimes, when using the HTC Music app and switching sound enhancements the app sometimes crashes, or audio stops completely forcing me to restart the device.
Also yesterday I was out driving for about 4 hours. I had Car Tunes app playing music and CoPilot Live 8 running for my SatNav, with the DHD plugged into my car audio using phono. I noticed that after unplugging and plugging in the audio cable, the audio would become very erratic. Car Tunes would always play audio full volume, but CoPilot (voice) would vary from being almost inaudible to full volume. This just seemed to happen randomly and would correct itself every now and again, then 'break' then 'fix' over and over.
On my way home yesterday the audio in both CoPilot and Car Tunes stopped working while plugged into phono. Audio is perfect without phono, but when phono is plugged in no audio can be heard. This is pretty strange as system sounds screen lock, volume adjust tone, etc. all work fine with phono plugged in.
I have noticed the sound enhancements crash bug with my 2 previous DHD devices as well as this one. One thing I have done to this is S-Off and BUZZ oc-uv 1.28 kernel.
Recap:
Yesterday while plugging phono in and out over and over (using satnav and leaving/re-entering car) audio would randomly become high/low in CoPilot only. Testing other music apps (to find satnav audio problem) found that Music app crashes/kills all audio/causes reboot of device when activating/chaing sound enhancement.
And now...
Phono out
- all sound works
Phono in
- no music audio (any app)
- no video audio (any app)
- no apps sound (Angry Birds, NFS game, etc)
- CoPilot voice OK
- system sounds OK
- if audio is playing before phono, when phono plugged in audio can be heard for split second
Has anybody else had issues like these? It doesnt seem to be a broken phono jack as some audio does come through it. I'm not up to speed with Android enough to know what handles different types of audio, or what could be the issue.

Does nobody else have any issue like this?
Could anybody who is up to speed with Android advise if this would be a corrupted system file of some description?

Well I didn't read all, but I think something is wrong when CoPilot is running...
On another day I was driving and playing music at same time, using the headset out to pluggin to my car. I needed to use GPS and start CoPilot. Selected a route and when the voice needed to say something the music simply was muted (or paused) ...
I didn't try too much cause CoPilot start to freeze my device and eventually I had to reset the phone with much difficulty...
Probably CoPilot is the culprit of all this
I have to try another gps program. Going to test Ndrive.
I miss so much iGO (it's not on sale for general users) and TomTom (not at all)

OK so another update on this.
Today I was out on another 5 hour journey and had CoPilot operating perfectly all day through my car audio (using phono). After around 3.5hrs of driving I got held up in very heavy traffic and was pretty much stationery so I decided to put on Youtube to pass the time with a few quick videos and noticed no audio was coming from it either so I used the volume buttons to make sure audio was at full.......turns out it was all the way down to mute!! This shouldnt have been as I always have youtube (and media volume in general) up to full. So I turn it up and it worked perfectly again. So I thought I would try my luck and test music....it was also now working flawlessly!!
This is really peculiar as I know I checked the volume of Car Tunes, HTC Music and Rockplayer numerous times each, before and after device reboots the other day when it wasnt working. It seems that all of a sudden the audio is now working again through phono, without any device reboots or reconfiguration of any kind.
One thing though.........I'm now back to having the high music / low CoPilot voice issue again.
Perhaps this may be some sort of CoPilot issue affecting audio on Android ?
Would love to hear some feedback or suggestions on this one lol

Music player randomly starting, stuttering when i plug my headphones in.

I have this problem not just with android, but wp7 also. Whenever i plug my headphone in the music player would randomly start, stutter, and skip songs. The only way to stop this is to pull my headphone out. This happens with every android build i have flashed for the past year. How can i fix this?

I have one set of in-ear phones that cause skipping (and false calls on winmo) during playback, and I can't explain it. My best guess is that the 3.5mm jack is leaking signal into the connector for the stock headphone controls, sending false signals that the phone thinks are commands from the remote.
Try some other earphones,if it doesn't happen then it's something along those lines.

I also get this with my sennheiser cx270's, sometimes its fine, other times it goes berserk.

Same, no other earphones seem to fix this, so I'm thinking it's the jack. It happens every once in a while.

[Q] Acer Iconia A500 headphone jack issue

Hey guys I was wondering if anybody else has had this issue occur with their device, recently my A500 has been playing audio from the speakers and headphones at the same time. This only happens on 2 out of 5 times, and when it does all I have to do is unplug the headphones and plug them back in. Yes, I have tried different pairs of headphones so that is not the problem. I need to know if this is an issue with the A500 itself( hardware) or if it could be a software issue just so I know whether to have it exchanged for a new one or not.
Appreciate the feedback guys

I'm sure it's unlikely to be a hardware issue as the headphone jack seems to work fine.
My vote is software bug. What are you using to listen to music? What steps are you taking to go from speakers to headphone - during playback? Before playback? Pausing playback, changing to headphones then starting playback?
Can you repeat any steps to get it to bug out on a regular basis or is it completely random?
It could be a music app bug or a HC bug. I have read others having similar problems since release but I don't believe anyone has found a solution/or the cause or done any testing.

When i start the music player app and plugin the jack and start music and then if the screen turns of or pause it and screen turns of and when i resume the same after sleep the music plays on both speaker and head phones this was not happening on 3.01 and happening on 3.1
i have tested this please confirm play music plug in the jack and then press power button which goes to sleep mode when u press the power button one more time and resume music this happens
One more thing is when i remove the jack the music app just pops up on the tool bar as in the status bar at the bottom

Hey matrix I tried reproducing your issue but it was fine, sound only came from the headphones. Btw I am using virtuousgalaxy rom, although when the issue started I was on virtuouspicasso

Having the same problem on my stock 3.1. Sometimes i need to unplug and plug in headphones multiple times to get it back to normal behaviour.

yup
Have had nothing but strange issues when using the stock music player. Sound coming from headphones/speakers at the same time, random fc's, horrid popping sounds from a perfect mp3 file, and my personal favorite feature - sometimes the player just starts up on it's own and blares music at inappropriate times.
Had these issues with stock music player since 3.0.1 up to the stock 3.1 build I am using.
My solution? Remove the stock music player from the system, download winamp, ???, profit

Problems with nexus 6p when listening to music

Hey guys
I just registered because I experienced some problems with my recently bought nexus 6p. I really like this phone but as soon as I start listening to music using headphones the bugs are invading my phone since I didn't find anything on Google I start this thread.
But let's get to my problem:
I plug in my headphones and start playing music (using blackplayer and Google music). When the screen is turned on the volume turns down itself (I can see the volume bar going down to zero like I'm pressing the button). Also sometimes the powerbutton stops working and I have to restart my phone long pressing the power button.
But also when the screen is turned out I experience some problems. One of the most annoying ones is that music stops and starts randomly (but only when headphones are plugged in!!!). The other bug is music stopping, display turns on and some female voice tells me "Bitte warten! (please wait)" and the screen is gray saying "initializing".
Has someone experienced similar problems? What could help? If you guys need any more information just tell me

I have none of these problems. Have you tried a different set of headphones?

Change your headphones or ensure that they're set up properly. I'm guessing they're wired.

I'm also running into this same issue. I have the latest updates on my phone. This happens about 25 minutes in to listening to media. I've heard that disabling "OK Google detection" fixes it. This hasn't worked for me.

Sounds like wired headphones with a faulty connection to the phones, or faulty buttons on the headphones. I have seen similar behavior with just a wired connection to an AUX Input. The connection on the wire was faulty and due to changing resistance, it looked to the phone like headphone buttons were being pressed. Could also be a fault at the headphone jack on the phone, but it was not in my case. Definitely try other headphones to help narrow down the issue.
