Description Josh Parsons 2004-07-04 06:42:12 EDT

User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.6) Gecko/20040510

Description of problem:
My toshiba laptop has an intel 82801CA/CAM AC'97 audio controller. 
Since upgrading to FC2 (from FC1) the sound card is sometimes silent
after a resume from power saving (I am using apm).  By silent, I mean,
no sound comes out, otherwise the driver appears to be functioning (no
errors from applications or in dmesg output, for example.) The sound
driver is snd_intel8x0.

Removing and reloading the snd_intel8x0 module always fixes the
problem until the next suspend / resume.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. While running gnome desktop, shut down computer with apm -s.
2. Resume by pressing power button.
3. play a sample with the play command.

  The same, under Fedora Core 3 with IBM ThinkPad T23 laptop


  Always reproducable (under ACPI):
1. Go to sleep by "echo 3 >/proc/acpi/sleep"
2. Resume bu pressing appropriate button(s)
3. Play any sample

Comment 2 Dave Jones 2005-04-16 00:12:46 EDT
Fedora Core 2 has now reached end of life, and no further updates will be
provided by Red Hat.  The Fedora legacy project will be producing further kernel
updates for security problems only.

If this bug has not been fixed in the latest Fedora Core 2 update kernel, please
try to reproduce it under Fedora Core 3, and reopen if necessary, changing the
product version accordingly.

Thank you.

  Unfortunately, the issue still occur under latest FC3 kernel. I open bug
155705 for it.
