Benchmark DAC3 HGC Device IO error after power outage.

Getting a very strange issue with a USB DAC.

Was working just fine with pipewire before the power outage, but after, nothing plays from the device and I just get constant IO errors from the audio interface control panel.

Tried the DAC with a windows laptop, device driver and everything works fine, so something broke in linux.

It was in the middle of a printing task when the power went out so I am wondering if the entire USB IO system just got hung in some weird half engaged error.

the DAC is the only USB device not working, it is recognized and labeled properly, just nothing plays and test sounds say IO Error.

Here are the results from lsusb

Reinstalled everything with this script

#!/bin/bash
for pkgName in $(cat packages.txt)

do
  pacman -S --noconfirm $pkgName
done
echo "Reinstalled all packages."

still broken...

I swear this DAC will be the death of me... but I finally fixed it.

For some weird reason it went into USB 1.1 mode after the power outage. It's gone into mute mode after a power outage without lighting the LED for mute so this doesn't surprise me.

For anyone that also has a Benchmark DAC3 HGC, Hold down the two input buttons to cycle through input USB versions.

The symptoms are device detected, no play back and 48Khz + 2X light illuminated. This apparently means the incorrect USB version is set.
Symptom is also visible in lsusb

Incorrect USB set:

Bus 003 Device 011: ID 1781:0e4e Multiple Vendors Benchmark DAC2 USB Audio 1.0

Correct USB set:

Bus 003 Device 002: ID 1781:0e4f Multiple Vendors Benchmark DAC2 USB Audio 2.0

Mod's you can mark this as solved.

For other users of this DAC, I have contacted Benchmark to make them aware of this recurring issue.
