Bad sound quality when playing scores

When I play any score on Musescore 4, it plays the sounds, but there are very frequent bumping and unstable sounds.

Thanks for the quick response. I have tested it again today and the glitches have almost gone (yesterday continuous jumps/jerks in the music). The problem today has almost gone completely. Even running playback in Musescore 3 and Musescore 4 at the same time now seem OK. Maybe it was a MS Windows 11 issue, and a combination of also running various screen narrators.

I also had playback sound quality problems after I installed MuseSounds - the playback hesitated several times on each bar, and there were frequent crackles - not unlike an old worn LP. I use Windows 10, and I found the fix was to increase the sound card sample rate. I.e. Go to "Settings" and click on "Sound" in the left-hand menu. Then click on the "Device properties" link under the Output section. Then, on the right of the screen is a link to "Additional Device Properties", which brings up the "Speakers Properties" window. (There are other ways to get to that!). Then click on the "Advanced" tab, to see a drop-down list of the available sample rates. I increased mine from 48000 Hz to 192000 Hz, and it fixed the problem immediately. Hope this helps.

... and now it has all gone weird again. The first pieces I played with the new sample rate were fine. Then I opened another score, and the instruments (e.g. piano, acoustic guitar) were high pitched with reverb! I tried switching instruments, and restarting with a new score, but the instruments were still messed up. Eventually I switched the sound card output back to the old sample rate setting, and it now seems fine for all of the scores!! I wonder what it will do tomorrow, but for now it is OK.

The issue some systems have with sample rate is almost certainly not about being too high or too low - it's much a mismatch between the sample rate of the device itself and sample rate info the OS communicates to MuseScore. It's the same sort of hiccups I can hear with a digital audio device running at 44.1 kHz when my system expects 48.
