Schitt DAC does not work

Greetings,

I am having difficulty getting my DAC to function properly on Arch Linux. I have performed several troubleshooting steps, including testing the hardware on both Windows and Ubuntu on the same PC, and have searched forums and Reddit for solutions with no luck.

1) [DAC not detected](https://bbs.archlinux.org/viewtopic.php?id=238699)
2) [Linux and USB Audio Class 2](https://bbs.archlinux.org/viewtopic.php?id=252602)
3) [Getting Schiit Modi 2 to work on Arch](https://www.reddit.com/r/archlinux/comm … k_on_arch/)
4) [Arch Linux users looking for good AMP/DAC Combo](https://www.reddit.com/r/archlinux/comm … dac_combo/)

I have confirmed that the ALSA and PulseAudio services are functioning, and have checked each sound card and output for any mute or low volume issues. I have also restarted the services and rebooted the system. I have updated the system with pacman -Syu and verified that the kernel has not reported any specific issues with this DAC. Additionally I have disabled USB autosuspend with a udev rule.

The output from aplay -l does not display Schiit Audio.

Re: Schitt DAC does not work

sudo dmesg | grep -iE 'snd|usb' 
pacman -Q linux
uname -a

there is some card that at least grabbed index 0. Do you have a custom modprobe config setting up audio card indices and if so what are the contents? Also post your udev rule.
