[mythtv-users] Audio - one channel doesn't play sounds

[Claude Boucher]

I have the wierdest audio problem with my fresh install of MythTV 0.17 
(FC3, latest 2.6.10 kernel, installed using Jarod's howto and updated 
with ATrpms).

My analog cable is connected to a PVR-250 through a coax cable and the 
quality is good for all 42 or so channels, except for one channel where 
I get video, but no sound at all.

It's wierd, because, I get sound on this channel on another TV connected 
directly to the coax and on my cable box. The card is probably not the 
culprit because I pulled the PVR-250 from my Myth box and I've put it in 
my Windoze box, where I get sound on this channel.

I don't know if it is relevant, but the channel (TV5) primarly airs 
programs from France which are transcoded to NTSC before they are 
broadcast on my Canadian cable system.

I use the on-board audio of my MoBo (an Asus A7N8X-VM/400) which uses 
the snd-intel8x0 driver with the following configuration in 
/etc/modprobe.conf

----- CODE -----
[...]
alias snd-card-0 snd-intel8x0
[...]
options snd-card-0 index=0
install snd-intel8x0 /sbin/modprobe --ignore-install snd-intel8x0 && 
/usr/sbin/alsactl restore >/dev/null 2>&1 || :
remove snd-intel8x0 { /usr/sbin/alsactl store >/dev/null 2>&1 || : ; }; 
/sbin/modprobe -r --ignore-remove snd-intel8x0
----- CODE -----

What should be my next troubleshooting steps ?

Thanks in advance,

Claude

similar problem (one in December 2004 and the other last February). but 
there were no answers.
