Hi,
I have the following code for my sound setup:
...
DPRINTF("got %d channels to allocate\n", chancnt);
if ((err = snd_pcm_hw_params_set_channels (handle, hw_params, chancnt))<
0) {
DPRINTF("ALSA: cannot set channel count to %d\n", chancnt);
return -1;
}
DPRINTF("trying to set pe
Hi,
I'm just trying to build the current cvs drivers, I do cvs compile with

Hi,
is there any documentation yet for the format of an asoundrc file?

Hi,
can it be, that snd_pcm_open in the alsa lib is not threadsafe?
Glame uses threads for all its plugins and if I have for example
one audio_in and one audio_out plugin, it can happen, that
snd_pcm_open is called twice at the same time. Wonderful things
happen in snd_config_expand and glame can
Hi,
I have the following code in glame's alsa_audio_out plugin:
char *pcm_name="plughw:0,0";
...
err = snd_pcm_open(&handle, pcm_name, SND_PCM_STREAM_PLAYBACK,
SND_PCM_NONBLOCK);
if (err<0)
FILTER_ERROR_RETURN("couldn't open audio device");
/* set back to blocking io *
Hi,
I just missed out a couple of API changes. Now I installed the newest
alsa version and I'm a bit lost. Usually I just did a alsactl store 0
after installation and had an uptodate version of asound.state.
Now I just get:
alsactl: get_controls:430: snd_ctl_open error: No such file or directory

Yeah, I appreciate that. And dividing it would probably help

Hmm, ok this is probably better than an error.

Nooo. What about adding a one liner:

Yeah
Hi,

yeah sure, thats what I said.

Exactly, but I just wanted to point out that sys is not the right location
to put asoundlib.h. Because all other files in there
