Hello,
I tried to get MPD setup on the vero4k, and I found that there seems to be an audio bug in the driver.
exception: Failed to open "default detected output" [alsa]
exception: nested: Error opening ALSA device "default"
exception: snd_pcm_hw_params_set_buffer_time_near() failed: Invalid argument
according to ALSA documentation that error means “configuration space is empty”, which means that the sound chip driver is not doing the right thing.
Obviously, sound playback does work with other software on the vero4k, such as kodi, so they are likely setting things up in a different way and do not stumble on the bug. Although, I have noticed before sometimes strange audio problems, depending on the source material I’m watching in kodi.
I tried to find the original upstream source for the amlogic audio chipset, but I only could find the imported source in the OSMC github tree. For example, this looks relevant. I suspect there may be some additional driver updates from upstream that maybe fix some of these issues, and maybe that needs to be re-imported from the amlogic driver tree. If not, maybe it needs to be passed up to them to fix?
