Hi Takashi,

ever since I have this workstation the plock/pop noise on playback start bugged
me. So far the only solution I have found is to disable the power_save which
I find acceptable on a desktop compared to the pops.

The alsa-info.sh output is can be found here:

The machine have ALC623 codec and the jacks are correctly discovered and they
do what they supposed to be.
When I have the headset connected to the front and audio is routed there the
line out (green jack) from the back still prodices the plock/pop.

Is there a known quirk for similar issue or a better way to handle it?

Thanks you,
Peter Ujfalusi
