Hello,
I'm using a PVR150 MCE. As long as I do not use the built-in FM radio
tuner, everything works as expected. But after using the radio tuner,
some TV channels do not have audio anymore. Sometimes randomely the
audio appears after some seconds or even minutes.
The problem seems to be that for some reason the audio standard is not
recognized correctly, because the problem can be workaround by typing
echo "AUD_STANDARD=4" | cx25840ctl -s 1
in the terminal. When I use this command when running a channel without
audio, the audio appears instantly. However, this is only a temporal
workaround, because when changing channels, the standard is re-set to 15
(0xf) which means auto-detection, and the problem occurs again.
Note, that the problem does only appear after the radio tuner has been
used once. Unloading and reloading the ivtv driver cures the problem
(until radio is used again).
Best regards,
Peter
