linux-2.6.30-rc2 - No sound (HDA Intel) avec resume

[Paul Rolland]

Hello,

For the first time, I can successfully suspend/resume my Dell laptop using
linux 2.6.30-rc2.
Unfortunately, after resume, xmms stays silent. I've tried to change the
master channel, and everything I can access in the configuration, but no
luck.
All other devices are resuming correctly, including the video while running
X and compiz, so this is quite good.

Is there anything I can do to help on this issue ?

At boot time, I have :
Advanced Linux Sound Architecture Driver Version 1.0.19.
HDA Intel 0000:00:1b.0: PCI INT A -> GSI 21 (level, low) -> IRQ 21
HDA Intel 0000:00:1b.0: setting latency timer to 64
ALSA device list:
  #0: Dummy 1
  #1: Virtual MIDI Card 1
  #2: HDA Intel at 0xefebc000 irq 21

When suspending :
Apr 20 21:26:21 tux kernel: HDA Intel 0000:00:1b.0: PCI INT A disabled

When resuming :
Apr 20 21:26:21 tux kernel: HDA Intel 0000:00:1b.0: PCI INT A -> GSI 21 (level, low) -> IRQ 21

Regards,
Paul

Are you using pulseaudio or direct ALSA or OSS access?

Try the very latest Linus tree, as some fix patches have been merged
after rc2.  If it still doesn't work, run alsa-info.sh with
--no-upload option before and after suspend, and attach the generated
files.  The script is found at
    http://www.alsa-project.org/alsa-info.sh


thanks,

Takashi

That's great to know. :-)

That looks pretty usual.

Please attach dmesg output including a suspend-resume cycle and /proc/iomem.

Best,
Rafael

Alsa.

I've been trying all your suggestions, but my machine is now refusing again
to resume, either using stock -rc2, or latest Linus's git tree...
Suspend is fine, resume seems fine, but the video is not restored anymore...

I've just seen -rc3 is out, I'll try to install it and have suspend/resume
working, and then I'll restart my HDA testing.

Thanks anyway for answering me !

Paul
