you can also use hint string to disable these features Hint Strings ~~~~~~~~~~~~ The codec parser have several switches and adjustment knobs for matching better with the actual codec or device behavior. Many of them can be adjusted dynamically via "hints" strings as mentioned in the section above. For example, by passing `jack_detect = no` string via sysfs or a patch file, you can disable the jack detection, thus the codec parser will skip the features like auto-mute or mict auto-switch. As a boolean value, either `yes`, `no`, `true`, `false`, `1` or `0` can be passed.
The generic parser supports the following hints: - jack_detect (bool): specify whether the jack detection is available at all on this machine; default true - inv_jack_detect (bool): indicates that the jack detection logic is inverted - trigger_sense (bool): indicates that the jack detection needs the explicit call of AC_VERB_SET_PIN_SENSE verb -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to pulseaudio in Ubuntu. https://bugs.launchpad.net/bugs/1208218 Title: intermittent left-channel audio distortion Status in “pulseaudio” package in Ubuntu: New Bug description: Since I installed this version of Ubuntu (Xubuntu 12.04 upgraded to Ubuntu Studio), I occasionally get crackly or fuzzy distortion in the left audio channel. It doesn't happen completely consistently, but it often happens while playing Flash videos in Firefox or editing audio in Audacity. It also happens pretty much every time I try to use Pure Data with JACK, and I can also replicate it by opening Audacity while using JACK (which will create distortion in all audio playing through JACK). But JACK doesn't need to be running at all for the problem to occur. Entering this command: rm -r ~/.pulse ~/.asound* ~/.pulse-cookie in the terminal is the only way I can fix the problem, and sometimes it takes several tries. I also have to restart some open applications after doing that to get them to play audio again. I tried the suggestions on https://wiki.ubuntu.com/Audio/PositionReporting , but that didn't solve the problem. I have PulseAudio 1:1.1-0ubuntu15.3 installed.
