Description Nomen Nescio 2007-08-05 10:56:40 UTC 
Most recent kernel where this bug did not occur: none
Distribution: Debian Etch
Hardware Environment: dual P2 celeron on BP6 (Intel 440BX), Diamond Monster Sound MX300 (au8830)
Software Environment: kernel.org kernel, suspend2 and -ck1 patches
Problem Description:
After a suspend-resume cycle (using Suspend2), my sound card doesn't 
work anymore. It works again after reloading the module.

dmesg, initial boot:
> Linux version 2.6.22-ck1
----8<----
> PCI driver au8830 lacks driver specific resume support.

dmesg, after resume, trying to use the card:
> vortex: ac97 codec stuck busy

Steps to reproduce: suspend-resume

snd-au88x0 acpi test patch (of 2.6.29 kernel)

Patch based on Takashi Iwai's patch, still unfinished, audio is working after resume and equalizer is initalized, but only newly started streams :( 

Already started streams produce this into dmesg:
ALSA sound/core/pcm_lib.c:1548: playback write error (DMA or IRQ trouble?)
ALSA sound/core/pcm_lib.c:1548: playback write error (DMA or IRQ trouble?)
vortex_adb_delroutes: route not found! 0x40
vortex_adb_delroutes: route not found! 0x2060
src alarm
vortex_adb_delroutes: route not found! 0x41
vortex_adb_delroutes: route not found! 0x2161
src alarm

If were no active streams before supsend all working just fine, and newly stared streams too. Maybe it is dma\irq issue but I don't have a clue. Any comments and improvments are appreciated.

Result of active stream during resume:
Playing WAVE 'audiodump.wav' : Signed 16 bit Little Endian, Rate 44100 Hz, Stereo
Suspended. Trying resume. Failed. Restarting stream. Done.
aplay: pcm_write:1442: write error: Input/output error

Great.  Could you reformat your patch to pass checkpatch.pl, and give a proper changelog and your sign-off to merge to the upstream?
Comment 5 Rafael J. Wysocki 2011-01-16 21:39:17 UTC 
What's the status here?  Has the patch been merged already?
