[Alsa-user] ice1712/envy24 experts, simultaneous independent channel recording

[Carl L. <gol...@ya...>]

Help ice1712/envy24 experts!

Below is my current asound.conf file (thanks to Steve
Mercier).  It defines 4 different stereo input
channels for A/D recording.  I noticed that if I
attempt to record on 4 channels simultaneously (4
different threads of course) only 1 channel will
record, the other 3 channels/threads will block.

I'm pretty sure the ice1712 chipset will allow
simulataneous multi-channel recording given the
software driver supports it.  

So does the alsa ice1712 driver support this?  Has
anyone gotten this to work?  Do I have to modify the
asound.conf file. Please advise. Thanks.
