Uname: 2.6.20-9-lowlatency #2 SMP PREEMPT x86_64 GNU/Linux (ubuntu feisty) This bug also happens with 2.6.19 from ubuntu edgy. When trying to run basically anything with wine, I get a brief click in my speakers, and the following in dmesg. Sound continues to work, but the wine process will be stuck in the D state.
