Yesterday, playwave gave a scattered sound (skips and many repeated sounds). Today playwave works. I could not get xmms working (neither yesterday nor today). This is 2.6.0-test9. xmms was fine in test5, running at half speed in test6 and test7, fine in test8, broken in test9. But I did not get the following messages: > /var/log/kern.log shows the following error messages: > > ---- > Oct 28 18:18:08 xxxxxxxx kernel: ALSA sound/core/pcm_lib.c:155: > Unexpected hw_pointer value (stream = 0, delta: -1314, max jitter = > 8192): wrong interrupt acknowledge?
