Changing the master volume in pavucontrol (or alsamixer) does not have any effect. The only way to change the volume is to go into the playback tab and change it for each application. The volume only changes when I set the master volume to 0 or when I increase it over 100%. In between there aren't any changes.

Running arch on a Lenovo X1 Carbon if that's of any use. I am using the arch default configuration files.

I posted somewhere else and was told to email this list as it could be a kernel bug.

kernel: 5.2.9-arch1-1-ARCH pactl info output:

Server String: /run/user/1000/pulse/native Library Protocol Version: 32 Server Protocol Version: 32 Is Local: yes Client Index: 13 Tile Size: 65472 User Name: martinmr Host Name: martinmr-laptop Server Name: pulseaudio Server Version: 12.2 Default Sample Specification: s16le 2ch 44100Hz Default Channel Map: front-left,front-right Default Sink: alsa_output.pci-0000_00_1f.3.analog-stereo Default Source: alsa_output.pci-0000_00_1f.3.analog-stereo.monitor Cookie: 1afa:f937

Let me know if the output from some other command is needed. Best,

Martin
