I thought of that, but with that you just get different problems.
E.g. dmix only works is all application wishing to play sound are run by
the same user. You would probably need some daemon to run the /dev/dsp,
Nope. See the ipc_perm option

Hello,
I am trying to export the controls to user space. I want to know the
complete list of controls
which ALSA expects the codec to support. For example, few are as below,
Master Playback Volume
Master Playback Switch
Tone Control - Bass
Tone Control - Treble
Line Capture Volume
Mic Capture
Hi,
Try to look at alsa-driver/alsa-kernel/Documentation/ControlNames.txt
But warning, this is not complete list, rather recomendation. Most
control names folows this recomendation, but there are some controls
for some soundcards, that have diffrent names.

If a PCM is already in SND_PCM_STATE_RUNNING, when is snd_pcm_wait()

When avail = avail_min.
1) Does this depend on period size in any way?
For example, if period size is 6000 frames, and I set avail_min to 2000
frames, will

there is no such list.
and lets get the terminology straightened out here before this goes
any further.
codec comes (in this context) from coder/decoder. that maps
roughly to what is more properly referred to
My driver is almost complete and I'm working to make it acceptable for
inclusion in alsa-driver. It drives 8 different cards and it raises some
problems. The main file is echoaudio.c and is contains all the control
interfaces of all cards. It registers only the controls a card has at
runtime, so

It looks like I have it working about 1/2 way. I compiled 1.0.3 and
along with its libs and utils got it installed on a RH9 system
(2.4.20). The drivers seem to load correctly, but attempts at getting
the mixer to work (alsamixer) seem to die in flames.

I believe better structure should be the way to go. And since you're the
one writing the drivers it is better if you follow the way you find it
more reasonable and better for other people to understand.

Hi all
I did this last night. The following is my analysis of the problem.
With full debug selected, the only message reported by the ALSA system is
ALSA ../alsa-kernel/core/pcm_timer.c:70: BUG? (rate != 0)
(called from d8c33a79)
That is, the assertion rate!=0 fails. This
