Red Hat Bugzilla – Bug 196631
No sound with acpi
Last modified: 2008-05-06 12:03:09 EDT
Description of problem:
Sound will not function if acpi is active.
Platform is Toshiba Satellite P015-S921 laptop.
CPU0: Intel Genuine Intel(R) CPU T2400 @ 1.83GHz stepping 08
CPU1: Intel Genuine Intel(R) CPU T2400 @ 1.83GHz stepping 08
Version-Release number of selected component (if applicable):
most recent as of date (1.0.4 ?)
Steps to Reproduce:
1. Install FC5
2. Boot with acpi=off
3. system-config-sound (play test sound): sound works
4. reboot, but remove acpi=off this time (acpi is on)
5. system-config-sound (play test sound): no sound
Cannot use acpi with sound.
(Note that I list the severity as high. This is because of potential serious
damage to hardware due to overheating with acpi off and sound working)
Sound with acpi running
Same results for 2.6.16-1.2133_FC5smp (after yum upgrade)
Also installed most recent alsa versions
Problem still remains
Similar to bug 182940 except different hardware
Created attachment 131514 [details]
log from system-config-soundcard
Oops: Satellite P105-S921 (typo)
That sounds like a kernel problem if you turn of acpi directly in the kernel and
it works then, so reassigning to that component.
Read ya, Phil
