@Raymond I've managed to get hda-analyzer work and with it I could do what you told me to do in #26.
If you want to get rid of the white noise, run as root the python script here attached. Or run the following commands: hda-verb /dev/snd/hwC1D0 0x0c SET_AMP_GAIN_MUTE 0x5180 hda-verb /dev/snd/hwC1D0 0x0c SET_AMP_GAIN_MUTE 0x6180 For your information, to make hda-analizer work I had to disable "HDA Intel HDMI": options snd_hda_intel probe_mask=0xfff2 ** Attachment added: "white_noise_fix.py" https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1252733/+attachment/4113457/+files/white_noise_fix.py -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1252733 Title: [XPS 12-9Q33, Realtek ALC668, Black Headphone Out, Left] Background noise or low volume To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1252733/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
