5.14 & 5.13 seem fine

Please read this:

[HowTo] become a Manjaro power user when you're a wizard at Windows but a N00b at Manjaro / Linux

Difficulty: ☆☆☆☆☆ Remember when you installed your very first Windows, added bells and whistles and then couldn’t see the wood for the trees any more and had to re-install? Well, you’re in the same situation now: You’re a N00b again! Embrace it! I know right now you’re thinking:

Why is this so much more difficult than Windows?

Whereas in 6 months time, you’ll be like:

Why can't I make Windows jump through fiery hoops like I do with Linux???

Especially the Linux has multiple kernels section, then stay on 5.14 and upgrade your kernel version often as you’re on the Stable development bandwagon.

@Altirix

did lsusb -s 3:5 --verbose as that gave me my bt/wireless car

Urgh! Probably a copy-paste error on my side, so thanks for that!

Ouch! Multiple of these! This device is not fully recognized.

@nikgnomic I need some help here: advanced audio device.

Summary:

• Device:

  @Altirix

    Device-1: 3-2:5 info: Roland VT-4 type: <vendor specific> 
    driver: snd-usb-audio interfaces: 4 rev: 2.0 speed: 480 Mb/s power: 500mA 
    chip-ID: 0582:021a class-ID: ff00 
  

• Only works on Kernel 5.14 and above
• lsusb -s 3:5 --verbose shows 11 UNRECOGNIZED features by the 5.14 kernel
• pacmd dump shows this for the device:

  set-source-volume alsa_output.usb-Roland_VT-4-01.iec958-stereo.monitor 0x10000
  set-source-mute alsa_output.usb-Roland_VT-4-01.iec958-stereo.monitor no

Ask:

@Altirix

the output route is correct but input needs to be one of the others that are available,

Am I on de right track here and how do I differentiate the additional ask:

@Altirix

Output routes : OUT | MIC IN | CARRIER
Input routes : MIX | WET | DRY

to use this as an audio interface you want to use the WET (with sound effects) or DRY (no sound effects) MIX will include the output audio
