On playback start there is a huge plock/pop noise via the green jack used in Line out mode. The only way I was able to fix it to set the power_save to 0 for the snd_hda_intel. Signed-off-by: Peter Ujfalusi <peter.ujfalusi@linux.intel.com> --- 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: http://alsa-project.org/db/?f=414b1b236fc73db386ad4f938bc3b304f6b30b05 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 sound/pci/hda/hda_intel.c | 2 ++ 1 file changed, 2 insertions(+)
