Hi All,
Just received my p3600 this morning and ive noticed some strange sound issues with it.
Rom Version : 1.23.405.2 - Date : 03/11/07
Radio Version : 1.38.00.11
Basically what happens is that when im playing back audio or video whether it be from windows media player or coreplayer, right at the beginning of the song i get a couple of low "blips". More like a very faint crackling, for example when we used to put the needle on old LP's. This happens pretty much everytime i play the song from the beginning. Also, when i use Coreplayer and select do benchmark, for the first couple of seconds i hear that same noise, then the video zooms past but no audio except for the very faint beeping crackling noise. Im just wondeirng if anyone else has come across this or if their Trinity does the same etc? Any fixes?
Thanks!
Ricardo
some more info
I listened to the sound it makes using headphones and it seems like to be the audio comes on, then goes off then comes back on suddenly and plays the music. This happens all very quickly, like within half a second. Also when i forward to the middle of the music video for example, it plays, then pauses as the sound kicks in, then plays normally after.
I though that it could have been the video but then i disabled the audio from within core player and then when playing the videos there was no pause or skip at all.
Does this sound like there is something wrong with the phone or a rom issue? thanks!
update
i know im posting alot about this, its just bugging me lol It seems like there is a delay with the audio system. For example, when using coreplayer, i try and lower the volume and there is about half a second delay from when i press the down button to when the volume actually drops. Same thing if i increase the volume. Also, when watching a video i have to adjust the manual A/V offset to -0.200 so that the audio is in sync with the video. Im just wondering if anyone else has this problem, if its normal for the rom or whether its a hardware fault? cheers

Hi, playing mp3 or wav with wmp or htc audio manager the sound is really bad. soon after starting it seems to stop and start (sometimes playing twice the same sound) while the mp3 goes on. It happens with USB headset and without.
Anyone else had such a problem?
Thanks in advance
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...)
This one has been bugging me for a while and for the most part I've just worked around it (by manually triggering the bug/fix myself first).
The situation is that X1 starts off at a particular volume level, and I start listening to music via PocketPlayer though from what I can tell it happens regardless. It sounds "ok", but noticeably flat? I dunno like a mono audio file even volume turned up, although I can't confirm that. Just describing.
OK the bug - if some kind of event happens, the volume suddenly jumps up, without actually changing the setting. So I'll be listening to music and if one of the following occurs:
1. receive or send an SMS/MMS
2. I toggle the phone function, i.e. turn off phone radio. when I turn it back on the volume doesn't change
the volume jumps up, and I have to say the music sounds much better. On the flip side, when the phone happens to ring, it's loud as hell, distorts like hell and annoys everyone in the process. The ringtone volume just sounds over-the-top.
Now I'm pretty sure it's not the music player because #2 (toggling the phone) seems to affect the volume already. The message box alert sound on toggling the phone seems louder the second time.
Anyone have or notice this issue?
The only volume threads I find are all about a low constant volume and don't sound like this one. FWIW I did try the reg changes anyway. It still varies.
It it just me, or is the stock rom shocking for poor sound quality?
Popping, clicking, missed notification sounds, cut/muted odd notifications - its all very irritating.
I've had to turn all the UI sounds off because of the popping/clicking noises that follow it.
I hope they fix it.
I´m glad, that I´m not the only one with this problem.
Did you try turning OFF the Audio Effects in Settings > Sound and Notification?
Also, there is a known issue with volume ramp-up for the first 1-2 seconds of alarms and notifications sounds. Will cause a very short sound to "not play" because the first second of the audio plays at zero volume.
I use my own MP3 files edited to add 2 second silence to the beginning of the playback, as a workaround. (Also separates the vibe and sound so the sound can still be heard clearly when vibe+sound is on - the original reason I added the 2 seconds. Because I like those sounds.
There is also at least one app to force full notification/alarm playback volume from the start of playback. Haven't tried it, others have posted about it here.

Yup, turned the Audio Effects stuff - first thing I did.
It doesn't do it on 3rd party roms, Only the stock rom. It's frustrating A-F
