I have a patch already which should make the device work correctly, and am issuing a PULL request for it this week. Regarding the analog audio, I'm not sure how you are testing, but if you are using tvtime, it is known that tvtime does not support analog audio for raw devices such as this. You need to run arecord/aplay in a separate window. Devin

I know about these tricks, I've used them successfully with Markus' em28xx-new driver. But with v4l-dvb it's as I said, audio is there but it's extremely quiet. If you have suggestions how I should try to diagnoze this, I'm all ears.

I would check your ALSA and PulseAudio configuration (in particular the mixer volume controls). Devin

And I've played plenty with the ALSA mixer, all the sliders that are there. Using em28xx-new instead of v4l-dvb, all else being equal, tv volume is fine. So there's gotta be a difference somewhere in the way em28xx-new sets up audio compared to how v4l-dvb does it.

That might help us identify whether it's an issue with the xc3028 tuner chip extracting the audio carrier or whether it's something about the way we are programming the emp202. Devin

Hello, That was a great idea. Tested with a Playstation2 and audio is ok. It's just TV input that has a problem. So I guess that means the issue is with the tuner chip. That's progress. Where do I go from here?

Ok, that's good to hear. What video standard specifically are you using? I suspect the core issue is that the application is not properly specifying the video standard, which results in the xc3028 improperly decoding the audio (the xc3028 needs to know exactly what standard is being used).

I'm from Slovenia, which is a PAL-B country. Tvtime can be set to either PAL-BG, PAL-DK or PAL-I, makes no difference. MPlayer has a whole bunch of options (PAL, PAL-BG, etc...), but again none of them make a difference. When the app is started, this appears in dmesg: xc2028 4-0061: Loading firmware for type=BASE F8MHZ (3), id 0000000000000000.
