Description:
Just installed Archlinux on a brand new Lenovo X1 Extreme gen 3. After install sof-firmware, the sound card shows us fine. Audio playback (speaker and headset) works fine. For audio record, I can see the following input sources in Pulseaudio: * Comet Lake PCH cAVS Headphone Stereo Microphone * Comet Lake PCH cAVS Headphone Digital Microphone Using any application to record audio (or webrtc), I am seeing: 1. the digital microphone works fine, and it corresponds to a mic array "around the display", but it captures a lot of the sound in the room 2. the stereo microphone, once my analog headset is connected, has very low input volume, even if I max out all volumes in pulse, the audio is very low, and barely audible The headset is a Bose QC25 and it works fine on the same machine with Windows, and on another Lenovo T460s running Archlinux as well. So the headset is not the issue. I have found many reports of audio issues with recent intel audio, but most of the time it's an old kernel (before snd-sof) or missing sof firmware, which is not the issue here. I haven't found any report of 'low volume' yet. Additional info: I have done a full reinstall yesterday, so all packages are up-to-date. |
