Sound trouble on certain HP laptop (in my case : dv7 1070)
When my laptop (HP dv7 1070e) is playing a sound, either there is no sound, either it is a very poor quality (with a kind of repetition of a short clip on a time interval of a few seconds).
The bug is independent from the speakers (for example, if I plug an headset, the trouble is still present)
Searching on the web, I found a tip to correct this : adding pci=noacpi at the end of kernel line in /boot/grub/menu.lst
Indeed, when acpi is disabled, the sound is played correctly.
However, I think this is not a good way to fix that trouble, because then, a CPU core is missing.
I know I'm not in that case, other persons I know have exactly the same problem with other HP laptop model (dv7 1035...)
Sorry for my approximative english.
Here are some information:
lspci | grep Audio
00:1b.0 Audio device: Intel Corporation 82801I (ICH9 Family) HD Audio Controller (rev 03)
Linux me 2.6.24-19-generic #1 SMP Wed Aug 20 17:53:40 UTC 2008 x86_64 GNU/Linux
(unmodified Hardy Heron. Note that I also tried 7.10, 7.04 and 8.10 alpha5 all 64 & 32 bits and no change)
Description: Ubuntu 8.04.1
If you need more, just ask me what.
EDIT : I found something strange...
acpi = on
sound under ubuntu = buggy
sound played through WINE 1.1.4 (winecfg => only when both ALSA and OSS are checked - if OSS isn't checked, sound is buggy) the sound is correct!!
