PulseAudio does not see cards which have only sources

[zap]

I have a Philips SAA7133-based TV card, which can work like an ALSA input device (for TV sound). It does not have any output devices, however. Here's the aplay -l and arecord -l output:

However, pavucontrol shows only two input devices - "YMF-754" and "Internal Audio".

Hmm, PA should support those just fine.

I'd guess that r39aa1cf94d43efaa80571b3f9d3dc56297f2f5be might fix your problem. Could you check that please?

Had reports from other folks that this fixes the problem. So closing now. Feel free to reopen if it didn't fix the issue for you.
