[mythtv] [mythtv-commits] Ticket #1598: AC3 passthru broken with some alsa drivers (eg. snd_usb_audio)

[Mark Spieth]

just had a look at the patch.
I probably would have not changed the interfaces to all these functions and 
used a comma separated alternate in the main device string to specify the 
passthru device name.
if you like I can make a patch that does this but it may be a while before I 
can do it.
have to back out lots of changes back to the way they were and also the 
settings as 1 string is enough.
just add another alsa preconfig option to select this case.

ALSA:default,iec958:{ AES0 0x02 }

the separate string in the audiooutputbase class can be kept as the passed 
string can be split on construct and assigned.

also I think Ive come to the conclusion that the multichannel and passthru 
reencode patch the way I did it in the first place is probably the way to 
go.
Ill try to find time to redo that patch due to the large changes in 
audiooutputbase.

cheers
