I'm using a headset mic/earphone combo. I have tested the same using a straight stereo pair of headphones.
None of the issues appear to affect the speakers, only the headphones. The symptoms are that when the phones are plugged in, whenever the audio is active (I assume that it sleeps when there's no audio being played), there is a constant crackling/popping/sizzling. This increases/decreases in line with the volume level and continues at a mid volume level when the master channel is muted. The speakers are muted as you would normally expect and apart from the noise, it exhibits the expected behaviour. I have no idea how to run the 'jack test', although I do have the hda_analyzer working. Let me know what dumps/logs you need. -- 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 [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
