Alsa error after running "arcd create" command

[greyivy]

Getting the same on a fresh install of Ubuntu 20.0.4.

We rolled back some changes that may have been causing this error in the latest commit. Would you mind checking again using the latest version? @zachpaul77 @greyivy

If you pull the latest changes from git you can update your locally installed arcd binary by running nimble install -y from within the libvf.io folder.

Still getting the same error unfortunately.

Hi @zachpaul77 I can confirm other folks have tried using 21.04. We aren't officially supporting that version of Ubuntu right now, only 20.04 LTS. If folks can make it work on that version we'll happily accept a pull request to add support! :)

@greyivy If you're on 20.04 and experiencing this problem would you mind sharing what model of CPU, motherboard, and GPU you are using? Also would you mind running this script for me and sharing the output here or through a Pastebin link?

#!/bin/bash
for d in /sys/kernel/iommu_groups/*/devices/*; do
  n=${d#*/iommu_groups/*}; n=${n%%/*}
  printf 'IOMMU Group %s ' "$n"
  lspci -nns "${d##*/}"
done

I pulled out use of --soundhw all in this commit due to deprecation warnings that were being generated and also the fact that running a VM with VFIO passthrough appears conflict with usermode audio permissions in ALSA. I'll try to work on a fix for this soon using QEMU 5.1+'s Jack feature or Scream.

I'm going to close this issue for now due to the removal of --soundhw until then.

If you'd like to try working on this some folks in the Discord are currently working on trying to get Jack working.
