Re-built mythtv with the changes   --enable-audio-oss  and  --disable-audio-pulseoutput.

Now the device options  ALSA:default:CARD=Intel  and  ALSA:sysdefault:CARD=Intel appear
in the audio settings panel.  With 'ALSA:sysdefault:CARD=Intel'  now I get
sound in LiveTV and playback of the recordings. However there is a new wrinkle.

It appears that mythtv is routing the PVR-350 audio output to alsa LineIn by default.
That is I do not have to run a cable from the pvr card to system LineIn port.
As I mentioned in my first post, the following option does not seem to be there..

------------------------------------------------------------
Hardware Decoding Settings:
[x] Use the PVR-350;s TV out/MPEG decoder
     Video device for the PVR-350 MPEG decoder:  [/dev/video16]    
     Program Guide Alpha:  [164]
[-]  TV audio through PVR-350 only
<cancel/back/Next>
--------------------------------------------------------------


My original problem is that if the alsa is configured as 6-channel one,
then LineIn port is lost. May be now that is not an issue..


thanks
