Debian: Can't set sample rate 44100, device doesn't support this value

Forums:

I installed moc on Debian 3.1 from it's packages, but it can't play sound - it shows this error
Can't set sample rate 44100, device doesn't support this value

XMMS/Noatunes works just fine. Any suggestions?

I tried both -R OSS and -R ALSA - same results...

I'm new to debian, I prefer FreeBSD where mocp works just fine....

It's an error from ALSA, not OSS, you must turn off the mocp server before switching to another sound driver (SHIFT-Q or mocp -x).

Try adding ForceSampleRate = 48000 to the config file (~/.moc/config) and restart moc.

Can you also compile and run this for me?

http://users.daper.net/~daper/pub//alsa_rate.c

Compilation: gcc -Wall -o alsa_rate alsa_rate.c -lasound
You must have libasound2-dev package istalled.

Please send me the result, it could help me fix that. Also, what is your sound card?

I have built-in sound card on VIA chipset for P-IV processor.

Do you have AlsaDevice parameter set to something else than "default" in your ~/.moc/config?

This option is available in 2.3.x.

it seems I have old version:
mocp -V
moc 2.2.1 Build: May 5 2005 15:12:19
Compiled with: MP3 OGG FLAC SNDFILE OSS ALSA DEBUG

may be i need to upgrade to newer one?

I downloaded newer version and tried to build from sources
it compiled fine, but when I invoke it, it conplains about

./mocp
FATAL_ERROR: No decoder plugins have been loaded!

same for mocp -R OSS

Probably no plugins were compiled-in. You need libmad0-dev et.c packages. The list of supported formats is displayed when ./configure finishes.
