[mythtv-users] Plextor ConvertX tuner missing sound

[Thomas Pedersen]

Had a look at that page, but doesn't seem to solve any problem..

Audio output device: /dev/dsp			(cat /dev/urandom > /dev/dsp works!)
-- Also tried; ALSA:DEFAULT

Passthrough output device: Standard

Mixer device: /dev/mixer
-- Also tried with mixer1 and without internal controls

Capture card setup - Audio device: /dev/dsp1	(Works fine with gorecord, where I get the sound from the tuner)

I'm able to get sound with MythVideo (using Internal player), if it's any help...

Have you taken a look at the Wiki page for sound?
(http://www.mythtv.org/wiki/index.php/Sound_Troubleshooting)

Which audio and mixer devices are you using for output?

I think this is a normal warning and harmless for the hardware and
driver... At least it does not cause me any problems.
