dmesg

Hi. Recently it seems like snd_hda_intel.power_save=1 became the default again in the kernel. On my hardware it causes constant popping though. In Windows I tried every solution/registry hack possible and the only thing that worked to fix it was to have muted capture mode running all the time so the sound never turns off.

I'm attaching lspci and dmesg. Maybe it's better to leave power_save off for this hardware.

Thanks,
Tod
