I have a CD jukebox made by Brennan model B2. It is Linux based.
# uname -a
Linux brennanb2 4.19.23 #1 Thu Aug 27 14:50:17 BST 2020 armv6l GNU/Linux
This is not a Linux desktop but more an embedded Linux application. I do have command line root access.
It appears to be recognized but I can’t get any sound out of it when it connects to the B2. The linux is completely ALSA based. The S/PDIF output from the B2 to the Q4 works find. The Q4 accepts the USB input from a Windows 10 machine just fine.
The USB device reports as:
T: Bus=01 Lev=03 Prnt=04 Port=01 Cnt=02 Dev#= 12 Spd=12 MxCh= 0
D: Ver= 1.10 Cls=00(>ifc ) Sub=00 Prot=00 MxPS=64 #Cfgs= 1
P: Vendor=262a ProdID=9113 Rev=00.01

C: #Ifs= 3 Cfg#= 1 Atr=80 MxPwr=100mA
I: If#=0x0 Alt= 0 #EPs= 1 Cls=03(HID ) Sub=00 Prot=00 Driver=usbhid
I: If#=0x1 Alt= 0 #EPs= 0 Cls=01(audio) Sub=01 Prot=00 Driver=snd-usb-audio
I: If#=0x2 Alt= 0 #EPs= 0 Cls=01(audio) Sub=02 Prot=00 Driver=snd-usb-audio
Does anyone know if there are any error in this or something special I have to do to get it work? Other people with different DAC products do get it to work as plug and play so the B2 does accept some DACs.
