Could you please make sure to avoid restarting the driver (switching between different presets where the driver is not included) and keep it running during your testing. Restarting the driver can lead to the behaviour you observed, i.e. no sound but the LOG suggest that everything is fine, and you have to reset the machine. > Any suggestions as to what I might to do to investigate further? As a first step please look into the the driver's report[1] and check—for example by using the system_shell in the window manager preset as starting point—the various 'outputs' eintries, especially 'outputs.mute' (should be false) and 'outputs.spkr_mute' (should be off). Those entries can configure the driver when set in the launcher[2] file directly but you normally should not have to alter them.
