No sound in HVR-1800

[karlec]

I have two capture cards, PVR500 and HVR1800, and I am using S/PDIF to my receiver. I never had any sound issues until I decided to use S/PDIF passthrough and used the following to get going http://ubuntuforums.org/showthread.php?t=843012 ;it still doesn't seem to be entirely stable cause when I shutdown my box I may or may not have sound altogether when it is turned back on.
My problem is that when sound is working on my machine, the PVR500 is the only one with sound, whenever I switch to the DVB tuner I get this crackling/shrieking noise.

Can anyone offer some pointers on how to fix this?

The PVR500 is connected via composite to my directv STB, the HVR is used with an OTA antenna.

Thanks

can you play the recording outside of myth, with say mplayer? This will help diagnose whether it is a system or myth problem. The commandline output from mplayer may give you some information as well.

You may also want to take a look and post your frontend logs from when you are playing back content with no sound.

Thanks for the reply. I can play a dvd with Mplayer using cli. The ATSC signals are the only ones with the sound issues. I'll post my frontend logs later.

Thanks for the reply. I can play a dvd with Mplayer using cli. The ATSC signals are the only ones with the sound issues. I'll post my frontend logs later.

yes, but what happens when you play one of those recordings with mplayer? You need to test on the same files that are giving you problems in myth to know for sure.

[newlinux]

Just as a quick test, temporarily disable pulse and then try playing a recording... Still could be a pulseaudio configuration problem.


killall pulseaudio

Now there is no sound at all in Mythtv.
