Your system information

Please describe your issue in as much detail as possible:

Switched from Windows to SteamOS and audio worked fine. Updating to Go Country removed audio. Bluetooth works perfectly. 3.5mm jack works, but is barely able to be heard when at maximum. Speaker audio doesn’t work at all. Unable to downgrade back to the original version of SteamOS as I don’t have a Steam Deck.

Steps for reproducing this issue:

1. Buy an Ayaneo Kun and update to latest BIOS via Windows
2. Switch to SteamOS
3. Audio disappears.

Please assist. Uploaded full system report to servers at 1524 PST for reference. Was on beta but no updates have resolved issue as of yet

Edit: Attached system report for ease
