especially how to specify the Mixer Card no and Mixer Device.
I have read the Linux journal article and both aplay, and alsaplayer are working.
My .asoundrc file is below. (BTW card 0 is the onboard via82xx which works fine).
Now it seems that xmms_alsa plugin wants a mixer card (= 0?) and mixer device ( =PCM).
I presume 'mixer device' is the equivalent of an Alsa simple mixer control.
But (Multiface) HDSP only seems to have a mono 'Chn' mixer control (with many indices 1 - to 18).
The via82xx does indeed have 'PCM' as a stereo mixer control and works in the Xmms/Alsa plugin,
i.e., this is a working setup
Audio Device:VIA 823x rev60
Mixer card: 0
Mixer device PCM
If I try
Audio Device: RME Hammerfall DSP + Multiface
Mixer card: 0
Mixer device Chn (<-how do I combine two indices to get stereo here?)
This is the error
alsa_setup(): Cannot set mmap'ed mode: Invalid argument. falling back to direct write
** WARNING **: alsa_setup(): Cannot set direct write mode: Invalid argument
Is the a way to configure two 'Chn' indexes n, n+1 and so that apps believe that a stereo simple mixer control exists?
