[HELP]: VLC 0.8.6a no audio from v4l capture card

Postby cwbshaw » 19 Jan 2007 18:59

Hi....

I had vlc 0.8.4 running on Fedora 3 with a Hauppauge WinTV/PVR (with MSP34xx chip) with line out on the WinTV card going into line in on a Sound Blaster card. With this I was able to tune to terrestrial TV channels and stream over the net.

Now, I have just upgraded our VLC machine/server to FC6 and vlc 0.8.6a. The new machine is a Dell Optiplex GX620 with an Intel ICH7 audio device (with Analog Devices AD1981B chip) on the motherboard. I am trying to take the line out of the Haup. WinTV card into the line in on this audio device, but VLC doesn't seem to pick up the audio.

I can hear the audio if I plug in headphones into the output of the audio device so the audio device is definitely receiving the audio on line in.....I just can't seem to get VLC to take video from /dev/video0 and audio from adev=/dev/dsp:audio=0 (as I did on the old machine) and stream over the net.

I have tried just about every form of adev using all of the dspX and adspX devices which appear to exist in /dev but no joy.

I could try using the Sound Blaster again, but I would need to change machines to do this, because there isn't enough PCI slots in the new machine.

I would welcome any suggestions as to what I might be doing wrong?

Or might there be a bug in this version of VLC?

Thanx in advance.

Chris Bradshaw.

Hi....

Problem solved.....I had neglected to exclude the btaudio and snd_bt87x modules from my kernel and it was automatically loading. Once I removed the module, everything worked fine.

The docs for these modules do say that they are only for audio capture (not playback) so I am guessing that the audio was being lost via these modules.

Apologies for wasted b/width.

Chris.
