I don't like PA starting automatically so I have that disabled and run speaker-test without it. I think the -D option bypasses it anyway. I have also run speaker-test through PA just to see and get the same result. > To narrow it down a bit, are you able to test any of the following: > - same card on Windows, > - same card on fglrx, > - same receiver with a different AMD card, > - same receiver with an Intel/NVIDIA card? I banished real Windows installs from my main desktop after a nasty incident some years ago. ;) I might be able to dedicate the card to a QEMU instance but I've never tried that before. I could easily try fglrx but I thought it didn't support multichannel? Or this new ALSA code fixes that too? Unfortunately I don't have any other AMD cards handy. I could try my wife's Ivy Bridge based laptop though. I'll report back soon. Regards, James
