Moode USB Output

Seems like maybe your speaker system is lying to Linux about its capabilities. I've never run across this and don't know how best to prove it [1]. I couldn't find any technical information worth spit about the PSB Alpha AM3 but after I read they claim "zero distortion" I didn't really expect useful technical information anyway.

One experiment which takes Spotify out of the equation is to transfer a 44.1 kHz track to the uSD card and see what setting changes you have to make to be able to play it through the speakers.

You can also try using Bluetooth out to the speaker. That, at least, would allow you to enjoy music while pondering

[1] Also, I've been known to be wrong before.

Oddly enough, I've just tripped over the same problem. I've just bought this xDuoo XQ-50 Pro for my headphone system, for easy switching between streaming and Bluetooth sound from the TV. On USB it reports:

Code:

Card 1, ID `Pro', name `XQ-50 Pro'                                                                                                                                                            
 Device 0, ID `USB Audio', name `USB Audio', 1 subdevices (1 available)                                                                                                                
   2 channels, sampling rate 8000..48000 Hz                                                                                                                                                  
   Sample formats: S16_LE                                                                                                                                                                    
   Buffer size range from 32 to 262144                                                                                                                                                      
   Period size range from 16 to 131072                                                                                                                                                      
                                                                                                                                                                                             
     Subdevice 0, name `subdevice #0'                                                                                                                       
                             

but will only play 48kHz files from Moode. First noticed when I played the test track, of course.

I'm using SoX resampling to make it work, but I think the Pi Zero W is getting a bit breathless, so there's a Pi 3B+ in the post for an upgrade.

I wonder if this is a result of these devices being primarily Bluetooth appliances, with USB being an add-on. Whatever, I can live with resampled CD quality, age and tinnitus haven't done my hearing any good.
