Hi Daniel, You are correct, the left speaker channel was at 0% volume.
After manually setting the Speaker control, both speakers work correctly. Output:- amixer -c 0 get Speaker Simple mixer control 'Speaker',0 Capabilities: pvolume pswitch Playback channels: Front Left - Front Right Limits: Playback 0 - 74 Mono: Front Left: Playback 74 [100%] [0.00dB] [on] Front Right: Playback 74 [100%] [0.00dB] [on] However, after reboot, the left channel resets to 0% again while the right channel remains at 100%. For reference, after reboot: amixer -c 0 get Speaker Simple mixer control 'Speaker',0 Capabilities: pvolume pswitch Playback channels: Front Left - Front Right Limits: Playback 0 - 74 Mono: Front Left: Playback 0 [0%] [-74.00dB] [on] Front Right: Playback 74 [100%] [0.00dB] [on] I did not change any sound settings manually before this; the system is in default state after installation. This looks like an initialization issue where the left speaker volume is incorrectly set to 0% at boot. Please let me know if further testing is needed.
