* hda-intel: ALC1150 (alc882 patch) produces constant noise on line-out port @ 2016-06-01 18:23 Maximilian.ammann 2016-06-01 20:03 ` Takashi Iwai 0 siblings, 1 reply; 3+ messages in thread From: Maximilian.ammann @ 2016-06-01 18:23 UTC (permalink / raw) To: alsa-devel Hello, I experienced weird behaviour on my "ASUS MAXIMUS VII RANGER" which has a realtek soundcard with the ALC1150 codec. The problem is that if the patch_882 is enabled I get a constant noise on the line-out port. I started experienced and noticed that when using the generic model the problem disappeared. Therefore the problem also disappeared when removing the folowing line in sound/pci/hda/patch_realtek.c: HDA_CODEC_ENTRY(0x10ec0900, "ALC1150", patch_alc882), I really would like to know whether this behaviour is expected or how I (myself) could fix it by creating a patch. alsa-info.sh output: Without alc882 patch: http://www.alsa-project.org/db/?f=3fdf926c64a02273e0e68035eeb94282ca44a 7df With alc882 patch: http://www.alsa-project.org/db/?f=336755aab10811bb0af5440dbda7b9cda3d9b 116 Thansk in advance, if possible it would be awesome if you could provide me some tips since I really would like to fix it myself as my very first patch.

Did you try to turn off "Loopback Mixing" mixer switch? This often stops such a noise. Takashi ^ permalink raw reply [flat|nested] 3+ messages in thread

Could you please explain why this happens and how to make this the default behaviour with this codec? ^ permalink raw reply [flat|nested] 3+ messages in thread
