8 channel output with USB 7.1 surround sound hardware - brunobronosky - 07-22-2024
In this thread we will discuss the Linux kernel support of icusbaudio7d devices.
This is from the first boot of a fresh install of r9.0.4
Code:
Host: moode
RPiOS: 12.6 Bookworm 64-bit | Linux: 6.6.31 64-bit
Model: Pi-3B 1GB
Audio: Pi HDMI 1
m o O d e a u d i o p l a y e r
Release 9.0.4 2024-07-06

Subdevice #0: subdevice #0The device used is Vantec NBA-200U USB External 7.1 Channel Audio Adapter but all of the CM6206 devices like StarTech.com 7.1 USB Sound Card work the same because internally they are virtually identical.
More to come...
