Broadwell rt286 volume too low

[benfuddled]

• Distribution and distribution version: Pop!_OS 22.04 LTS (I've also experienced this issue on multiple versions of Fedora and Ubuntu.
• Desktop Environment: Gnome 42
• Kernel version (uname -r): 6.2.6-76060206-generic
• PipeWire version: 0.3.70

Description of Problem:

My laptop (an HP Spectre X360 13-4002dx) speakers and headphone jack output audio at extremely low levels, to the point where initially I thought they weren't outputting audio at all. It was only when I allowed over-amplification in gnome-tweaks and holding my ear up to the speaker that I realized there was sound coming out.

However, when I plug in a pair of USB headphones (not via the headphone jack) sound levels are within expected range. Same thing if I output sound via HDMI to a television.

Note: Myself and a few others had this problem and initially filed bugs independently with pipewire, but a commenter seemed to think it may be a problem with the UCM file for this device.

Hoping someone here can shed some light on the issue. Thank you!

Could you try to increase levels in alsamixer ?

Looks like we're dealing with a userspace app problem. I see that offload streams have their volume settings set to 0%, that is endpoints: Offload0 and Offload1. Perhaps the app deviated from the default endpoint?

Also, could you try playing audio but with values of Media0 Playback Volume and Media1 Playback Volume increased beforehand?
