Sound problem - 2 devices


Well I cant seem to get my sound working. I just recompiled my kernel to include support for my TV Tuner card, so it shows up as having 2 sound devices, the TV Tuner's chip and my emu10k1 (sb live).

The problem is that i cant seem to get it work properly. I've never had a problem getting sound goin until i enabled the "bt878 audio" support in the kernel for my TV Tuner card.

What would fix this?

Is this on your slack system? If so, can you give us a bit more info on how you enabled the card? I too have SB Live, and I too recently added a TV tuner, however I had no problems at all like yours. Post up your modules.conf and rc.modules (relevant sections only please) and tell us whether you are module-ing your devices or not.

Cool

the emu10k1 is built directly into the kernel. Seperately i have modules for the bttv driver.

my modules.conf only loads my nvidia driver, but my rc.modules is as follows:

/sbin/modprobe bttv tuner=2 card=41 radio=1
/sbin/modprobe tvaudio debug=1
/sbin/modprobe tvmixer debug=1
/sbin/modprobe dpl3518

I have enabled in my kernel an option for bt878 audio, should i not have this?

wow i am stupid. This option in the kernel is only if ur tv card handles it's own audio...

maybe i should have rtfm more carefully....lets see if this works!

ok i recompiled and didnt include the bt878 options (under the sound menu), and even with no bttv modules loaded the sound device still shows up, so i assume it is a product of the video4linux.

Ok. everything is defaulting to sending audio to the wrong device it seems. When i startx KDE gives me this error from the sound server saying that it is unable to achieve 44100hz and that it will send audio to null device. I am running as root during this time, and permissions arent an issue.

Kmix shows 2 devices, Brooktree bt878 audio, and Creative SBLive - Emu10k1.

I dont know what to do to get sound working aside from completely disabling anything and everything related to my tv tuner support lol.
