Windows 10 qube migrated from R4.1 has crackling and interrupting sound

Windows 10 qube migrated from R4.1 has crackling and interrupting sound.

On R4.1 the sound was working fine almost always, but I had similar situation a couple of times with this qube, too. Rebooting qube would have solved the issue, but on R4.2 on the same hardware the sound is always crackling.

Opening Volume control in dom0 does not change anything.

Any ideas how to fix it?

[How to file a helpful issue](https://www.qubes-os.org/doc/issue-tracking/) ###… Qubes OS release 4.2.4 (R4.2) ### Brief summary Windows 10 qube migrated from R4.1 has crackling and interrupting sound. On R4.1 the sound was working fine almost always, but I had similar situation a couple of times with this qube, too. Rebooting qube would have solved the issue, but on R4.2 on the same hardware the sound is always crackling. ### Steps to reproduce Recover Windows 10 qube from R4.1 (with last working QWT before its removal). ### Expected behavior Qube works as it was on R4.1. ### Actual behavior Sound is crackling, interrupting for microseconds or something. ### Additional information - Opening Volume control in dom0 does not change anything. - Changing sound settings in Windows, quality, sampling rate, disable any audio effects does not change anything. - The `audio-model` for the Qubes OS is `ich6` (the only working one for now in Qubes OS)? ### Other reports of this bug Different users have this problem on forum, none is solved: Sound crackle windows 10 qube - User Support / General - Qubes OS Forum https://forum.qubes-os.org/t/sound-crackle-windows-10-qube/23550 Crackling Scratchy Sound in Windows Qube in Qubes 4.1 - User Support / General - Qubes OS Forum https://forum.qubes-os.org/t/crackling-scratchy-sound-in-windows-qube-in-qubes-4-1/13540 ### Workaround To use USB or PCI physical audio-card passthough would probably workaround this bug.
