@mikosenigma: this is quite strange: there are many reasons why one speaker may not work, but it is more difficult to explain why muting one loudspeaker would make the other louder.
Did you confirm that your hardware works correctly, if you run Windows? If this is the case, you can run "qashctl" and adjust a large number of parameters, of which: 1) in mixer "PulseAudio", the Master Playback Volume might be zero for one side 2) in mixer "acp3x-es83xx", you may look at: - Headphone Mixer Volume, Headphone Playback Volume, DAC Playback Volume: do you have the same setting for both sides? - DAC Mono Mix Switch: it should be unchecked (but if I check it, I get the same sound from both loudspeakers) - Left Headphone Mixer Left DAC Switch, Right Headphone Mixer Right DAC Switch: both should be checked - Left Headphone Mux, Right Headphone Mux: you should have the same setting (I have "lin-rin with Boost and PGA") As far as I understand, the other settings either are symmetrical, or are used just for input, capture, or similar features. You may also try "qasmixer", it shows many nice sliders and some switches in the bottom of the screen, but frankly I am not sure that I may be of any use for you. You may also try to check whether there is really no sound from the left speaker, or just a very faint one (which may indicate a problem with some volume setting). Using Audacity, you can create a sound with a muted right channel to check that. As I said, I had to try many tweaks before have my loudspeakers to work, and I don't remember exactly which ones. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux-oem-6.8 in Ubuntu. https://bugs.launchpad.net/bugs/2073049 Title: No sound on Huawei Matebook D14 AMD since Linux 6.8.0-38 [regression] Status in linux package in Ubuntu: In Progress Status in linux-oem-6.8 package in Ubuntu: Invalid Status in linux source package in Noble: Fix Released Status in linux-oem-6.8 source package in Noble: Fix Released Bug description: This laptop has had non-functioning internal sound (based on AMD Renoir) until Ubuntu 24.04, which made it work thanks to a bugfix in the kernel.
