Volume intolerably low on Intel audio device (broadwellrt286 card)
- PipeWire version: 0.3.53
- Distribution and distribution version: Pop!_OS 22.04 LTS (I've also experienced this issue on multiple versions of Fedora, including Fedora 36.
- Desktop Environment: Gnome 42
- Kernel version (
uname -r
): 5.17.15-76051715-generic
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.
On older versions of Pop_OS (which used pulse) and Ubuntu 22.04, my volume levels are normal. My sense is that my sound driver is reporting incorrect DBs, that maybe pulse was working around and pipewire doesn't. But my knowledge of linux audio is unfortunately rather shallow. I've tried changing some of the properties listed here (https://pipewire.pages.freedesktop.org/wireplumber/configuration/alsa.html), including setting ["api.alsa.ignore-dB"] = true, but no dice.
Additional Info:
I've attached a pw-dump, as well a link to an alsa-info here:
