I'm having some trouble using dmix with a multithreaded program that
has to close and reopen the sound device. Closing and opening happens
in different threads.
I'm using alsa-lib 0.9.4 and I've got dmix set up to be the default
device. That is, my .asoundrc looks like this:
pcm.!default {
> plugin "alsa". Trying defaults. snd_pcm_open: Permission denied (quattro1)
> Failed to initialize plugin! -
I had similar problems. Sometimes i could access ALSA devices as a normal user,
and sometimes only as root. It seemed to change (for the worse)if I unloaded all
the sound modules and t

Hi. I originally posted this to the alsa-user mailing list, with no responses.
Hope you guys can help me.

Hi,
When trying to compile the latest cvs version I got the following errors:
In file included from ac97_codec.c:1:
../../alsa-kernel/pci/ac97/ac97_codec.c: In function `snd_ac97_mixer_build':
../../alsa-kernel/pci/ac97/ac97_codec.c:1394: structure has no member named

Hi there,
Just wondered how I can apply the cool feature - dmix
- to my own program to mix sounds? for example, after
I compile my small c++ program, I can run it one at a
time:
./a.out TestMusic.wav
The thing's that how I can mix sounds when I run:
./a.out TestMusic01.wav &
./a.out TestMusic02

I botched my previous patch for the UA-5: the altsettings of the audio
interface would be ignored because bInterfaceSubClass isn't set to
USB_SUBCLASS_AUDIO_STREAMING on that device. This patch corrects this.
