[Bug 125264] Re: Sound broken after resume of Suspend - Toshiba P100

[madbiologist]

Is this still occurring in Ubuntu 10.04 "Lucid Lynx"?

This issue might be fixed upstream in kernel 2.6.35-rc5.

    ALSA: hda - Restore cleared pin controls on resume
    
    Many codecs now clear the pin controls at suspend via snd_hda_shutup_pins()
    for reducing the click noise at power-off.  But this leaves some pins
    uninitialized, and they'll be never recovered after resume.
    
    This patch adds the proper recovery of cleared pin controls on resume.
    Also it adds a check of bus->shutdown so that pins won't be cleared at
    module unloading.
