Trying to get a USB DAC to work on Galaxy note, got a kernel that recognises, making progress but I'm wondering if our problems are with ALSA.
Is anybody here working with ALSA and can anyone point me to the latest build?
I've used various programs on Google Play, and get usable output, but I cannot get anything to play using alsa_aplay. Get a write error even after stop mediaserver.
Any tips, or discussions going on anywhere? Not finding much with google.
All comments appreciated.

Hi,
I was checking the Rhodium Android forum, and found the following developing work:
http://forum.xda-developers.com/showthread.php?t=1076884
Is anyone able to check if this may work on our blackstone?
I'm happy with the FRX6, but audio shutering and lack of BT make it not suitable for daily basis.
If someone make this fixes to work, pls post a tutorial!
Thanks
Audio stuttering has been 'worked around' ages ago, see http://forum.xda-developers.com/showthread.php?t=999544
As for BT, i don't know about that. In the second post there's something about Broadcom an TI chips, so if the Blackstone has a Broadcom chip why not just try it out. The instructions for the setup are all there in the thread
Let us know how it turns out

Why can't You try on your phone?
i had test libhtc_acoustic with acoustic supported kernel.Sound working but only on call speaker but not on loud speaker or audio jack.Need for viruscrazy to update the lib and kernel to support all devices.Audio stutter still there.Still no clean fix when u disable battery service during listen to mp3.You will end up listening to mp3 not knowing your phone going to die.Audio stutter will be fix when there are no resource and excessive service running
I just purchased an A501, rooted it and am running the Alexander III rom, (very nice job on the rom!!!)
I was hoping I would get the bluetooth Headset HSP profile in the new rom but sadly it was not there.
A little research has shown that there is a Bluez driver plugin installed and various bluetooth libraries, my question is can I potentially just replace these libraries with bluez libraries from another rom that has the HSP profile?
I really need to get the bluetooth headset profile working on this A501, and am willing to pay a bounty for help in getting it working
Sorry to say, it doesn't work... as with most other Tablets.
Just using some libs from another ROM isn't going to work either, unless they are extremely similar... and all ROMs similar enough to try such a stunt are almost definitely broken as well.
Sorry, but you'll have to roll your own BT stack if you're desperate enough to try... I'm not gonna.

Still doing a little research on this. I discovered, in the Bluetooth folder, a couple of files pertaining to what Acer has deemed "black listed", which simply means, certain brands and models are not allowed to work with bluetooth. System/etc/bluetooth/
Also noted, if you modify the files, you need to make changes in a couple of other module files (android_bluetooth_ScoSocket.cpp). The info in the above files tell you where to look.
Not sure why Acer black listed those devices. Legal reasons maybe? Plain incompatibility? Who knows.
My dev skills, are not quite up to modifying .cpp files. Probably enough to muck things up really good Not to mention, I would have no way to test them. But when I get a chance, I'll see what's in them.
Of course most of this pertains to Auto pairing, so might not be of much use. As with the .so files in the Bluez folder, you'll need to de-compile them first to see what's in there.
Also, I saw some bluetooth apps onn the market that some folks had some success with getting HSP. Not the off/on widgets but an app itself. Might want to give them a try and see if you can get the headsets to connect.
Additionally, it seems bluetooth headset problems seems to be across all devices, and not just the a501, but Zoom, Transformer and Thrive as well. Hit and miss with what works. Most issues say the mic doesn't work.
I tried a couple of the apps with no joy on my plantronics earpiece but one of the widgets actually connects...for just 2 seconds...then disconnects...I think the capability is there and you are correct there is some file manipulation that needs to occur...
I have a friend in Egypt that is very good with android bluetooth, he is working on another project right now but when he finishes his current project I will send him these files...he might be able to figure it out ...
Hi,
I have been searching around the interwebs for a 4.3 ROM for jfltexx, but i can't seem to find any that lets me create application for LE. I have tried the latest cyanogenmod and slimbean ROMs (failes the hasSystemFeature check), and also looked around for any mentions on this subject. From what i have found i can't see that anyone has confirmed BLE support on their ROM. I might have missed something though, so does anyone know how i can BLE functioning on my Galaxy 4?
Much appreciated, Henrik

Forgot to say that i can detect BLE devices with the bluetooth scan in settings, and pair with them. Only application fail the BLE check.

For me, it's even worse. BT LE devices can not be detected with my i9500.
As far as I learned, Android failed to deliver proper BT-stacks. Not sure if any developer cares about this. I didnt see any development in any forum
With "BLE Heart Rate Monitor" from play store, I can connect my heartrate belt with BT LE. But my fitness apps can not connect with it. It seems that they use the improper original Android BT-stack (afaik)
Hello all,
I am new in Android dev.
For an specfic device test purpose, I want to write an APP that gets the audio from the microphone and plays it back through the head-phone.
I was just wondering if this is possible at all (to get the signal in real-time and play it back through the headphone).
Would you please direct me, share any ideas you have or even introduce me a library or something that I should start with.
Many thanks in advance.

Hey there everyone. I recently purchased one of these devices to work with my Police Scanner to make it available online for my community to help teach bad weather.
I've got everything installed and windows shows no other updates available however when I check the audio input there are two listed. The Intel one and the USB one. I'm not sure what the USB one is but I've connected my phone playing music and neither of them show the audio bar getting anything. I've made sure the MIC is enabled and I'm not sure what to do from here. Not sure if I got a bad unit or if there is a known issue with a fix.
Any help anyone can offer is greatly appreciated.
If anyone can offer advice on this I would greatly appreciate it.
