Hi all.

I have problem with openning a device for playback.

this is working code: snd_pcm_open(&handle, "default", SND_PCM_STREAM_PLAYBACK, 0);

but this is not working: snd_pcm_open(&handle, "hw:0,0", SND_PCM_STREAM_PLAYBACK, 0);

I get this is: Device or resource busy

PS: I have been started the `phonon' (KDE sound daemon), and the amarok (audio player).

My question: what I need to do for correct open "hw:0,0" for multiply playback ?

Make sure that nobody else is using the device at the same time. "hw:0,0" requires exclusive access to the device.

You can see who is currently using your sound device(s) using this command:

sudo fuser -v /dev/snd/*
