Playback heavily out of sync with ASUS Xonar U5 and U7 without tsched=0
Playback is heavily stuttering and out of sync between for example front/rear channels when using ASUS Xonar U5 or U7 USB soundcards. Currently using tsched=0 fixes the problem for me but on recommendation by a fellow over at diyaudio.com I#m now filing a bug here.
