I was able to resolve the problem tonight. The monkey wrench thrown into the works was that once I'd figured out how to configure the mixer properly, the audio mux on the card got put into as muted state, so no change I made in the mixer had any effect. Eventually I had all the levels cranked up so high I could hear the sound leaking through the mux, and suspected that was the problem. (Plugging my amp directly into the tuner card and getting no sound confirmed it.) Previously, before I had the correct card type specified for the driver I was getting muted audio. I thought once I had the correct card type that the problem was solved. Apparently not. I'm not sure what flipped it back into mute mode. I tried unloading and reloading the driver. That didn't work. But running: v4l2-ctl -d /dev/video2 -c mute=0 -c volume=63 corrected the problem. Oddly enough, the MythTV documentation on configuring sound: http://www.mythtv.org/docs/mythtv-HOWTO-7.html actually had good info on how to set up the mixer. And explained why I was hearing sometimes echoed audio and sometimes audio that leaded the video by a second or two. The trick was to mute the microphone (or line-in) source, so it doesn't get directly passed to the output mixer, but also select the mic as the capture source, which is accomplished in different ways with different mixer UIs. Also, the default /dev/dsp device was the correct input device to use all along. All this makes me appreciate the relative simplicity of installing the PVR-500. Definitely the way to go for an analog tuner. -Tom ------------------------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
