This has happened a few times on different channels now. Sometimes when I change channel, I get no audio. I wait for about 10 seconds but it doesn't fix itself. I then change to another channel, which works fine and then when I change back to the channel that had no sound, it still doesn't but after a few seconds it comes on, at which point the picture freezes for a couple of seconds before everything settles down.

I think this happened a couple of times whilst the attached logs were being made, but the last instance was from
2009-04-15 22:59:44.718750 (in Mediaportal.log) where I was watching BBC4, changed to BBC3 and had no audio, changed back to BBC4 and then back to BBC3 which got it working.

Never experienced this problem with v1.0.0. I'll try using the MPC audio decoder to see if that helps.

Not experienced this problem since switching to the MPC audio decoder.
