Bug ID: 257082
Summary: Sound with Scarlett Solo 3rd intermittently cuts off
for very short periods of milliseconds.
Product: Base System
Version: 13.0-STABLE
Hardware: Any
OS: Any
Status: New
Severity: Affects Only Me
Priority: ---
Component: usb
Assignee: usb_at_FreeBSD.org
Reporter: hodong_at_nimfsoft.com
Hello.
Sound with Scarlett Solo 3rd intermittently cuts off for very short periods of
milliseconds within a few minutes. At this moment crackling noise occurs.
Sometimes there is no sound for 0.0x seconds.
I tried it on Linux (kernel 5.10.x) and MS Windows 10 as a test, and it works
fine.
