[Debian-eeepc-devel] Bug#574844: SNDRV_PCM_IOCTL_RESUME failed: Function not implemented

[Trent W. Buck]

Package: eeepc-acpi-scripts
Version: 1.1.10
Severity: normal

On a 1005P, if I shut the lid while mplayer is playing, and open the lid
and Control_L (to wake it), the speakers start spewing noise instead of
music.  Mplayer reports:

    [AO_ALSA] alsa-lib: pcm_hw.c:709:(snd_pcm_hw_resume)
    SNDRV_PCM_IOCTL_RESUME failed: Function not implemented

I believe that the lid event triggered a "pm-suspend --quirk-s3-bios"
via this package.

I could mute the speakers using alsamixer.  I then killed mplayer, and
ran the following until it stopped removing modules:

    for i in `lsmod | grep ^snd | cut -d' ' -f1`
    do sudo rmmod $i
    done

After this, unmuting the headphone channel and starting a new mplayer
resulted in music playing normally again.

I run Debian's linux-image-2.6.33-2-amd64 (2.6.33-1~experimental.4)
from experimental (i.e. I haven't recompiled it).  According to lspci,

    $ lspci | grep Audio
    00:1b.0 Audio device: Intel Corporation N10/ICH 7 Family High Definition Audio Controller (rev 02)

According to powertop, it's a "hwC0D0 Realtek ALC269".

According to lsmod (note: after aforementioned rmmods),

    $ lsmod | grep snd
    snd_hda_codec_realtek   243343  1
    snd_hda_intel          20211  4
