Public bug reported: I have encountered an issue with Ubuntu 21.04 where any audio output is piped to the mic in incorrectly. This is happening by default when using the 3.5 aux in & out ports. This would be great if I wanted a loopback but I don't. This fundamentally breaks my workflow and would like to find a resolution, but no idea what else to try.
This seems to happens on both the default pulseaudio server & force switching to pipewire Microphone is a vmoda boom pro PC is a lenovo thinkcentre m910q tiny which has: - 1x mic jack - 1x combo headphone/mic jack - running on the realtek alc294 I have tested this by recording with parec with the physical microphone switch off and on, with a youtube video playing in the background. I have also done the same test with microphone detached from headphones and it still is piped through. All audio is recorded, which to me seems to confirm there is an issue/bug somewhere in the audio stack. I have only found one other example of this happening, where that was on a different distro (manjaro) & reporter said to use usb, where I am using aux/ 3.5mm plugs. However, that thread just stopped with no resolution: https://forum.manjaro.org/t/all-the-sound-is-going-through- my-microphone/41760/10 I have attempted the tests in that thread, and I can confirm that there is some sort of software cross talk happening here. I have also attempted both recommendation for hdajackretask, and setting custom quirks in alsa-base.conf in this thread: https://superuser.com/questions/1312970/headset-microphone-not-detected- by-pulse-und-alsa hdajackretask was tried to get the combo headphone/mic jack to work, but did not find any setting to get that to work. Using two separate plugs, headphones & microphone do work, so not an issue with the pin setup. I tried the specific quirk for this codec, alc294-lenovo-mic, but that did not work either. Have tried: options snd-hda-intel model=alc294-lenovo-mic options snd-hda-intel model=headset-mic options snd-hda-intel model=dell-headset-multi In all variations, but this does not solve the issue of all of my audio is getting sent through the input for no good reason. I am not sure how else to debug at this point and looking for any insight possible.
