tvtime: audio routing from external (usb) TV card

Err.... Sorry for reporting this as a bug. It is of course more of a feature request,
just couldn't find where to ask for it (the original site looking very dead by now).

Looking at the attachments in this bug report, I noticed that an attachment was not flagged as a patch. A patch contains changes to an Ubuntu package that will resolve a bug and this attachment is one! Subsequently, I've checked the patch flag for it. In the future when submitting patches please use the patch checkbox as there are some Launchpad searches that use this feature. You can learn more about the patch workflow at https://wiki.ubuntu.com/Bugs/Patches.

@dforsi: if actually take a *look* at the patch, read and understand it, you will quickly notice that the patch in question is a goddamn HACK, as it is said in the message text: "Hack in the sox as a kind of audio router"! It should NOT be applied to the project's code unless you're in dire need for audio in such a case and don't mind to remember installing sox.

I would post it in the message body if not for formatting, which would make playing with it harder.

I adapted a patch from Markus Rechberger to add this feature (I had to modify it to work with generic USB audio devices and PulseAudio). It works fine here under Karmic, but with a small delay between video and audio.
You can find a deb package in my PPA if you want to test it.

Whoopie's patch, tested by installing tvtime from his ppa. (running Karmic amd64 here, using a WinTV-HVR 950, which worked great in tvtime except without sound) works perfectly for my setup. I was running tvtime with a script like the following:

#!/bin/sh
tvtime &
sleep 1
sox -r 48000 -b 16 -c 2 -t ossdsp /dev/dsp1 -t ossdsp /dev/dsp

And that worked although with horrendous lag between the sound and the video, it wasn't even watchable, but with Whoopie's patch tvtime works as expected with no hacks. Thanks much Whoopie, hopefully this can be integrated into the official ubuntu version in the near future

With this patch I can't start tvtime when my USB headset is connected.
tvtime quits after it finds the headset:

I have Lucid Lynx with tvtime 1.0.2-5ubuntu2 and the same problem with a USB Microphone. tvtime starts only if I unplug the Microphone, but when I plug it back in, I have to reconfigure my audio settings every time.

Please fix someone this bug.

Hi, I think we have a problem with this patch.
I was before in Ubuntu 8.04, and with the "workaround" of sox I was able to get my Hibryd card work with tvtime.

After this patch (or maybe pulseaudio) I can't heard any sound from tvtime.

USB headsets work again with the fixed tvtime-1.0.0.2-alsa.patch from #340769.
Can you please update it?

I've just tried tvtime since some time, and though it worked before now it exits with message "Channels count non available" and mentioning my USB webcam for some reason which should be not involved at all. It seems that message only presents in a patch which contains an URL for this bug. That's why I am writing here now. My report is bug 752980

Please note, that I have a PCI tv tuner card, not an USB based one though.

So what I ment that this fix seems to introduce problem for me which renders tvtime unusable :(
