[PATCH] ALSA: usb-audio: Add dB range mapping for Sennheiser Communications Headset PC 8
by Takashi Iwai 03 May '21

03 May '21

From: Timo Gurr <timo.gurr(a)gmail.com> The decibel volume range contains a negative maximum value resulting in pipewire complaining about the device and effectivly having no sound output. The wrong values also resulted in the headset sounding muted already at a mixer level of about ~25%.

[PATCH] ALSA: hda/realtek: ALC285 Thinkpad jack pin quirk is unreachable
by Sami Loone 03 May '21

03 May '21

In 07d9e69cf34a ("ALSA: hda/realtek: fix static noise on ALC285 Lenovo laptops") an existing Lenovo quirk was made more generic by removing a 0x12 pin requirement from the entry. This made the second chance table Thinkpad jack entry unreachable as the pin configurations became identical. Revert the 0x12 pin requirement removal and move Thinkpad jack pin quirk back to the primary pin table as they can co-exist when more specific configurations come first. Add a more targeted pin quirk for Lenovo devices that have 0x12 as 0x40000000. Tested on Yoga 6 (AMD) laptop.
