Hello again. I was able to get my internal speakers working for my HP Pavilion Dv4 laptop by following the advice I found in the alsa-devel archives. That advice seems to have worked for quit a few people who found it by a post I made to the Ubuntu Forums. But now, after I have upgraded my Ubuntu from version 8.10 (when sound worked) to version 9.04, sound no longer works correctly. I have some detailed information about the sequencing and the specific error. Attached is an alsa-info.txt output. Here's what I'm seeing (extracts from dmesg/kernel logs): Apr 29 15:13:17 Harlindon kernel: [ 19.937190] HDA Intel 0000:00:14.2: PCI INT A -> GSI 16 (level, low) -> IRQ 16 Apr 29 15:13:17 Harlindon kernel: [ 19.937270] HDA Intel 0000:00:14.2: setting latency timer to 64 Apr 30 09:37:09 Harlindon kernel: [ 19.941675] HDA Intel 0000:00:14.2: PCI INT A -> GSI 16 (level, low) -> IRQ 16 Apr 30 09:37:09 Harlindon kernel: [ 19.941750] HDA Intel 0000:00:14.2: setting latency timer to 64 May 1 16:06:01 Harlindon kernel: [ 19.852324] HDA Intel 0000:00:14.2: PCI INT A -> GSI 16 (level, low) -> IRQ 16 May 1 16:06:01 Harlindon kernel: [ 19.852398] HDA Intel 0000:00:14.2: setting latency timer to 64 May 1 16:13:43 Harlindon kernel: [ 20.950985] HDA Intel 0000:00:14.2: PCI INT A -> GSI 16 (level, low) -> IRQ 16 May 1 16:13:43 Harlindon kernel: [ 20.951060] HDA Intel 0000:00:14.2: setting latency timer to 64 Commit Log for Fri May 1 16:41:58 2009 [Upgrade to Ubuntu Jaunty 9.04] May 1 17:11:05 Harlindon kernel: [ 20.318416] hda-intel: unable to grab IRQ 0, disabling device May 1 17:11:05 Harlindon kernel: [ 20.318517] HDA Intel: probe of 0000:00:14.2 failed with error -16 May 1 17:14:18 Harlindon kernel: [ 22.977762] hda-intel: unable to grab IRQ 0, disabling device May 1 17:14:18 Harlindon kernel: [ 22.977828] HDA Intel: probe of 0000:00:14.2 failed with error -16 May 1 17:18:49 Harlindon kernel: [ 21.105013] HDA Intel 0000:00:14.2: PCI INT A -> GSI 16 (level, low) -> IRQ 16 May 1 17:18:49 Harlindon kernel: [ 21.105087] HDA Intel 0000:00:14.2: setting latency timer to 64 May 1 21:15:14 Harlindon kernel: [ 19.776991] HDA Intel 0000:00:14.2: PCI INT A -> GSI 16 (level, low) -> IRQ 16 May 1 21:15:14 Harlindon kernel: [ 19.777893] HDA Intel 0000:00:14.2: setting latency timer to 64 May 2 09:22:01 Harlindon kernel: [ 20.540543] HDA Intel 0000:00:14.2: PCI INT A -> GSI 16 (level, low) -> IRQ 16 May 2 09:22:01 Harlindon kernel: [ 20.540619] HDA Intel 0000:00:14.2: setting latency timer to 64 May 2 09:26:04 Harlindon kernel: [ 19.819578] hda-intel: unable to grab IRQ 0, disabling device May 2 09:26:04 Harlindon kernel: [ 19.819677] HDA Intel: probe of 0000:00:14.2 failed with error -16 May 2 10:37:28 Harlindon kernel: [ 20.175934] hda-intel: unable to grab IRQ 0, disabling device May 2 10:37:28 Harlindon kernel: [ 20.175999] HDA Intel: probe of 0000:00:14.2 failed with error -16 May 2 13:26:27 Harlindon kernel: [ 20.610591] HDA Intel 0000:00:14.2: PCI INT A -> GSI 16 (level, low) -> IRQ 16 May 2 13:26:27 Harlindon kernel: [ 20.610666] HDA Intel 0000:00:14.2: setting latency timer to 64 May 2 16:57:23 Harlindon kernel: [ 19.885497] hda-intel: unable to grab IRQ 0, disabling device May 2 16:57:23 Harlindon kernel: [ 19.885575] HDA Intel: probe of 0000:00:14.2 failed with error -16 May 2 18:20:18 Harlindon kernel: [ 22.605977] hda-intel: unable to grab IRQ 0, disabling device May 2 18:20:18 Harlindon kernel: [ 22.606042] HDA Intel: probe of 0000:00:14.2 failed with error -16 What is damned peculiar is that is has sometimes worked (as you can see above). I can find no pattern however. I HAVE downloaded an compiled the latest alsa-driver-snapshot. That last reboot has the same unable to grab irq error. Any suggestions are greatly appreciated. -- Guy Stalnaker, I^2@DOIT, 1210 West Dayton Street, Room 3209 CSS, Madison WI 53719-1220, jstalnak@xxxxxxxx, work 608.263.8035, cell 608.235.4718, fax 608.265.6681, page page-guy@xxxxxxxxxxxxxxxxxxxxxx _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx http://mailman.alsa-project.org/mailman/listinfo/alsa-devel
