Hi, I have a minor problem with sound falling out and becoming white noise in mythtv every now and then. I currently solve this problem by running this command: v4lctl -v 1 -c /dev/video0 setnorm PAL-BG
This command currently runs on a crontab every hour on the hour on my backend system. This solves the problem for me, but needless to say it's not exactly an elegant solution. The problem is caused by saa7134 not being able to "guess" what audio-carrier setting to use, and thus reverting to the (I think) default, which is 6.000 Mhz. For me to have sound, I need to have it at 5.550Mhz. dmesg: saa7134[0]/audio: audio carrier scan failed, using 5.500 MHz [last detected] saa7134[0]/audio: audio carrier scan failed, using 5.500 MHz [last detected] saa7134[0]/audio: audio carrier scan failed, using 6.000 MHz [last detected] <- this is when sound falls out Previously, one could set this as a module option (modprobe saa7134 audio_carrier=5500), but this was removed about a year ago by the video4linux2 maintainers in favour of a more flexible solution - namely enabling this to be set in user-space instead. This enables a user to, for example - tune several different channels with a different audio-carrier for each channel. However (afaik) mythtv uses the old behaviour, and does not set audio-carrier on channel change - which leads me to my question: Does any of you guys know of a way to tell mythtv to execute a command (v4lctl bla bla..) on channel change, or on startrecord? /Steffen -- non-recovering mythtv-addict.
