Comment (by ttcoder):
With some search-engine help I've found this [http://cgit.haiku-
os.org/haiku/commit/?id=02b3446666d04e12e8fe8caea11c6f2f0962fd8c
multi_audio_test.cpp] sample file. It works with ioctl()s on the
/dev/audio/hda..... pseudo-file. Great, I thought! But no cigar :-/..
Here's my findings..
{{{
~/Desktop/haiku_GIT/MULTIAUDIO_test> ./multi_audio_test
/dev/audio/hmulti/hda/0
multi_audio_test: Could not open "/dev/audio/hmulti/hda/0":
Device/File/Resource busy
}}}
Ok so the media_server needs to be shutdown before accessing the driver..
Is that a bug, i.e. something to report in this ticket (or another one) ?
If that's a "feature" then it's definitely a show-stopper for us...
Then I did...
{{{
~/Desktop/haiku_GIT/MULTIAUDIO_test> hey media_server quit
(....)
~/Desktop/haiku_GIT/MULTIAUDIO_test> ./multi_audio_test
/dev/audio/hmulti/hda/0

}}}
but did not hear anything coming from the speakers...
(yep it works fine otherwise: I'm listening to music right now, after
restarting media_server).
Will leave interpretation to somebody knowledgeable..! Much appreciated in
advance thanks :-)
