[mythtv-users] Audio from SAA7134

Fri Nov 24 13:42:09 UTC 2006

Thanks guys.
I remember loading the saa7134-alsa driver before and getting an error
where it couldn't find it. But that must have been an older version.
That worked well. I also did the muting command afterwards.

Doing a arecord -l it displays my card finally. A big step.

I still get no sound from the tuner though. I remember having to issue
some commands to get the Line-in working so I do that (From
mythtv-HOWTO):
$ amixer set Master,0 100%,100% unmute
$ amixer set PCM,0 100%,100% unmute
$ amixer set Line,0 75%,75% mute captur
$ amixer set Capture,0 100%,100% captur
$ su
# alsactl store

But upon issuing the alsactl store command I get a bunch of kernel messages.

That terminal window is frozen, can't get out. I open another and do a
"arecord -l" and it freezes when it gets to where it should display my
tuner info.

I have to forcefully power off the computer, and all the settings I
did aren't saved.

This is on a new install I did last night too, with no other changes
that could mess things up.
Am I not supposed to configure the sound like this with saa7134-alsa?

Thanks,
Andy
