how to enable multiple playback streaming?:
I am manipulating bios verb pin table, for special analog hardware, using
ALC886 and kubuntu / 64bit.
I need a number of separate stereo (only stereo) i/o's
I have correctly configured inputs:
4. single stereo adc port-C 1Ah
5. single spdif input 1Fh
I have configured 3 independent stereo outputs, but ALSA is joining them
into one pcmC1D0p device.
I have tried this on win7 and I got all associations as a separate devices.
in my kubuntu 12.4LTS I have only one playback device.
Mixer is showing even more then needed number of volume controls,
But there is only one playback device.
it seams, all 3 outputs are connected to single DAC.
I have tried to buildup more input devices - this is working good.
I can have up to 3 (pcmC1D0c, pcmC1D1c pcmC1D2c)
I can also have 2 outputs if I enable spdif-out.
But there is no separate DAC assignment to separate devices resulting from
Is it possible to get independent DACs devices under ALSA?
or else is no such configuration possible and I have to use single multiple
