After a while of playing=20 sound it stops with: pcm0: chn_write(): pcm0:virtual:dsp0.vp0: play interrupt timeout, channel d= ead showing up in dmesg. After that no sound is played and Amarok skips throug= h=20 tracks quickly (it "plays" sounds to fast)... After setting dev.hdac.0.polling=3D1 sound works again. =20 This is with a custom kernel that has sound compiled in and without debuggi= ng=20 options. =20 A known good kernel is from ~ 13 May while the bad kernel is ~ 1 day old. = =20 Some further information: # dmesg | grep hdac hdac0: mem 0xe7000000-0xe70= 03fff=20 irq 21 at device 16.1 on pci0 hdac0: HDA Driver Revision: 20100226_0142 hdac0: [ITHREAD] hdac0: HDA Codec #0: Realtek ALC888 pcm0: at cad 0 nid 1 on hdac0 pcm1: at cad 0 nid 1 on hdac0 pcm2: at cad 0 nid 1 on hdac0 hdac0: mem 0xe7000000-0xe70= 03fff=20 irq 21 at device 16.1 on pci0 hdac0: HDA Driver Revision: 20100226_0142 hdac0: [ITHREAD] hdac0: HDA Codec #0: Realtek ALC888 pcm0: at cad 0 nid 1 on hdac0 pcm1: at cad 0 nid 1 on hdac0 pcm2: at cad 0 nid 1 on hdac0 and # grep '^C.*FLAGS' /etc/make.conf CFLAGS+=3D -DNDEBUG Is there anything I can do to assist diagnostics?
