I believe it's in the setup interface under the device section. Go to your PVR (/dev/videoX), and check the box for independent muting of L/R channels. Just a shot in the dark, but I remember reading that this option was for situations similar to your description.

I thought the problem was fixed, but it is not. Next possible culprit... ivtv? as someone suggested here? ___ mythtv-users mailing list mythtv-users@mythtv.org http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users
Re: [mythtv-users] Audio - one channel doesn't play sounds
Thanks for the advice, but the problem seems to be elsewhere.
I followed your advice and pulled a Sound Blaster Live from one of my
other computers. I disabled the on-board audio and installed the SB in
my Myth box (including editing the /etc/modprobe.conf for a 'emu10k1')
but no luck.
I still get the same intermittent problem with some channels some of the
time. It happens most of the time with channel 15, but I also got a
video-only recording last night on channel 21 (a CBS affiliate).
We'll see what happens with 0.18...

I had the same problem with my onboard sound and snd-intel8x0 under
alsa. Only one channel would play back.
What should be my next troubleshooting steps ?
My troubleshooting step consisted of purchasing an inexpensive sound
blaster. Problem solved.
I really think there's something off with that driver on some onboard
sound cards.

If the sound card is playing two channel audio then it probably isn't
an alsa issue. Try a few different ivtv driver versions and see if it
changes, or at least play the recordings on different hardware to rule
out a cature problem.

Re: [mythtv-users] Audio - one channel doesn't play sounds
Both sound cards are fine. I get correct sound from all MP3s, DVDs, CDs. Live and recorded television is usually fine, except for the problem I mentioned earlier. And the bad recording from last night doesn't play on my windows box or on a bootable KnoppMyth front end (v. 5A12) on a second computer. I will check out the newer versions of ivtv. As you guessed correctly, I use an older (0.32q, which I picked up at ATrpms.net) version of the driver.

[mythtv-users] Audio - one channel doesn't play sounds
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 21 || :
remove snd-intel8x0 { /usr/sbin/alsactl store /dev/null 21 || : ; };
/sbin/modprobe -r --ignore-remove snd-intel8x0
- CODE -
What should be my next troubleshooting steps ?
Thanks in advance,
Claude
PS: I searched the list before posting and I found two threads with a
similar problem (one in December 2004 and the other last February). but
there were no answers.
