Hello!

Can anyone confirm if the voice path and "voice" PCM device are broken in the today SDK / OS releases?

I can't get any sound from both the earpiece and mic when running the new OS.

I've tested it in both my own application and the AudioLoopBackSample.

https://github.com/blackberry/Core-Native-Community-Samples/tree/master/AudioLoopBackSample

Was able to reproduce this on a second Dev Alpha A device: was able to hear-record sound before updating it to .339, sound disappeared after updating.

Ruled out a possibility of an SDK bug, this is OS-related.

we have similar problems with our app, with analyzes the microphone input. we are investigating this issue at the moment

I've opened a ticket in the BlackBerry Jira: https://www.blackberry.com/jira/browse/BBTEN-660 . Maybe you can participate there too?

Thank you for your input, hope we can sort this out

[guru2000at]

have you marked the issue as private? i can not see it :/

[aesteral]

I've certainly did not intend to but it looks like that issue in triage by RIM are inaccessible by other users

[guru2000at]

ok.

can you post more information, if rim provides it

[aesteral]

I certainly will, but there is still nothing though. However, BlackBerryDev confirmed on Twitter that this is not an intentional API change.

Please check this patch for the latest correct way of working with the audio device:

http://trac.pjsip.org/repos/changeset?reponame=&old=4316%40pjproject%2Ftrunk&new=4316%40pjproject%2F...

You'll need to call:

if ((pb_result = snd_pcm_plugin_set_disable (pcm_handle, PLUGIN_DISABLE_MMAP)) < 0)

after openning audio device.

snd_pcm_plugin_set_disable (pcm_handle, PLUGIN_DISABLE_MMAP) helped. Thank you.
