Bug ID: 445161
Summary: Kwave eats 100% CPU while recording
Product: kwave
Version: 21.08.3
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: thomas.eschenbac...@gmx.de
Reporter: sm...@smurf.noris.de

SUMMARY
Kwave busy-loops and thus eats 100% CPU while recording.
STEPS TO REPRODUCE
1. open the Record dialog
2. (possibly) select a PulseAudio input
3. click Record
OBSERVED RESULT
The computer's fan starts up, noising up my recording, because kwave eats 100%
CPU.
EXPECTED RESULT
The computer's fan stays quiet.
Data point: Audacity requires ~10% on this machine, using the same settings.
