Hi there, I have the following setup: Laptop ==> Thinkpad USB-C Dock Gen2 3.5mm jack ==> active speakers Now, after a firmware update on the USBC dock the firmware was updated to using USB audio interface2 before the fw update the dock used UAC1. Now, with UAC2 there is no sound on the dock´s 3.5mm audio jack anymore. The strange thing, pavucontrol does show the dock output device, it is not muted and when playing sound the volume meter actually does show something, but the speakers remain silent.... Is there anything I could do on the pulseaudio level? From the view of pulseaudio the dock audio jack seems to work, but the speakers are silent. The speakers are ok. I´d like to share my settings (comments stripped) on a pastebin for better reading: daemon.conf: https://pastebin.com/wrhDe881 default.pa: https://pastebin.com/DV56Hdyx pacmd list-cards: https://pastebin.com/2VurNtZN pacmd list-sinks: https://pastebin.com/mW4muH8Q /sbin/lsmod: https://pastebin.com/PZ19CLQz Software used: Linux kernel 5.16.6 pulseaudio-14.2-4.2.x86_64 alsa-1.2.4-3.13.x86_64 Thanks a lot for any hint !
