Yes, there are other topics and post pointing to issues.
No, and yes. Because if I attach USB audio device (from the correspondent sys-usb) to the qube in which I want to hear audio, then everything is OK with Linux qubes, while in Windows qube it is the same as in the post you found.
But, if I use external USB audio device as general audio device for all qubes, then recently, probably starting from Qubes 4.1.1 latency became horrific - about 50 sec (yes, not ms), while under Qubes 4.1 it was zero.
