Alsa/myth problem

[feddersen]

Hi
I have installed mythtv on a computer and everyting works, except sound on live tv. I can see the picture but no sound. Music and video works ok.
kdetv and xawtv also works with sound when i unmute line in

I think i have isolated the problem somewhat,

In gstreamer when i test default output plugin i get a error saying
failed to construct test pipline for alsa

when watching tv with xawtv with line in muted
i try to run aplay /dev/dsp or /dev/adsp
dsp gives me a error kode
adsp gives out a lot of loud noise..

When trying modprobe saa7134-alsa
and then aplay /dev/dsp1 the sound is ok in xawtv, but still not in mythtv even when set to dsp1...

HEEEELP MEEEE!!! Pleeeese

MythTV doesn't appear to support alsa (as I learned the hard way). You'll need to load the alsa-oss modules:

# modprobe alsa-oss-pcm
# modprobe alsa-oss-mixer

Then the /dev/dsp setting in MythTV will work as it's supposed to.

Well don't have those modules.

I think the problem might be with the dsp device... since it's not working with aplay. How can I fix that? or reinstall it or something..??

Here is something i tried.. It returns the same error as myth backend does when I watch tv..

MediaPc:~ # cat /dev/dsp > /dev/dsp
cat: /dev/dsp: Inn/ut-feil (Translation: In/out-error)
MediaPc:~ #
