I was too, but hey it is just another way that it does not work. :'(
Also it is possible that it was/is a non starter as there is no internal output from your card,hence no /dev/dsp.
There is another option, to kill PulseAudio and then try it again (it might be a long shot)
Code: [Select]
sudo killall pulseaudio
After that I think I will be ready to throw in the towel.

Not stepping on SeZo's toes .. but ..

If I were you I'd remove oss-compat .. every time I've installed it, it plays havoc with the PulseAudio controls

Not to mention oss-compat CANNOT work without loading snd-pcm-oss (the driver they've removed from the kernel) to provide /dev/dsp  ::)  <--- this is the EXACT reason I don't think you'll get xawtv to work, as CAPTURING from OSS's /dev/dsp seems hardcoded into xawtv.

Actually .. thinking about it, it may not have been oss-compat, it may have been oss4-base (tried that too) .. but as I said oss-compat is broken in recent versions of Ubuntu/Mint/Peppermint anyway, so no point in having it installed.

All I'm saying is if you notice any audio problems, try removing oss-compat which is broken anyway.

According to <a href="http://http://pkgs.org/ubuntu-12.04/ubuntu-universe-i386/oss-compat_1_all.deb.html">this site[/url] oss-compat is available for Ubuntu 12.04.1 LTS
Quote
This package ensures that Open Sound System support is provided in some way. On Linux, it enables the ALSA compatibility modules. On other kernels where OSS is the default interface, no action is taken.

The purpose of this package is for applications that only support OSS

to depend on it, hence preventing common "/dev/dsp not found" errors that would confuse unexperienced users.


Yeh that's what it's SUPPOSED to do  ::) .. but it can't provide /dev/dsp without first modprobe-ing the snd-pcm-oss (and if wanted snd-mixer-oss and snd-seq-oss) kernel module .. which doesn't exist  ::)

Try doing:
Code: [Select]
modinfo snd-pcm-oss
you'll see what I mean .. the other 2 still exist, but thanks (sarcasm) to the people at Ubuntu, the important one (the one that makes oss-compat work) doesn't.

I don't blame you but no one can fault you for effort :)

From what Mark is saying it looks like xawtv is not gonna work no matter what we do  which is frustrating because we're so close, I don't know if you and Mark think it's worthwhile exploring other options with this card, if not I'll understand and thank you both for your efforts


Many thanks

Give me a day or two to test other distros, and/or look for a kernel with snd-pcm-oss compiled in.

That's the ONLY way (AFAIK) to get) oss-compat to work .. and therefore xawtv.
(on either card)

ok no problem but just out of curiosity what about Cheese or guview would getting either of them to work be an easier solution. I'm not double guessing you Mark, I'm just curious :)

So what happens with guvcview ?

I don't know, I'm at work at the moment but I'll try that and report back

I haven't really had a close look .. but it looks like bluetooth might be causing an issue, can you remove the bluetooth device, reboot, and try again.

Also, make sre you've tuned in the video with xawtv first.

[EDIT]

If that helps .. you might also want to try cheese without the bluetooth device connected.
