rear speakers not working, maybe Alsa OSS problems

Hi All,

I just recently got a new set of speakers:
http://www.ncix.com/productdetail.php?sku=6934

I got them hooked up ok and everything seems to work fine. I can hear
all four speakers in xmms, but not in myth. I'm using alsa with the alsa
driver snd-cs46xx.

The way I understand myth is it uses /dev/dsp and /dev/mixer to speak to
the soundcard which is the Alsa OSS compatibility layer in my setup.
Could this be a problem with the driver not working properly with this
layer? The reason, I assume, it works with xmms is xmms uses alsa
directly. Any thoughts?

btw, my soundcard is the Herceles Game Theater and I am using mythtv
from cvs updated as of yesterday.

Cheers,

Scott

This depends on which output plugin you're using in xmms.

xmms is using alsa as I thought I made clear.

I don't know whether this will solve your problem, but I'm working on a
patch for mythtv to use ALSA directly. I've gotten the TV part working,
now I'm rewriting mythmusic audio output to share the same code.
Hopefully I'll get it all working this weekend.
