I don't recall this happening previously... it was a little laggy in raising/lowering the volume but it didn't actually interrupt the music. I may try a fresh install to see if there's any improvement
I actually noticed this too last night. Most of my players have maximum volume all the time (downstream amplifiers control the volume), but one in an old radio in the kitchen uses in-player controls. I rarely listen to Spotify on that one, but did just last night. I wondered if it was simply that I'm using a Pi Zero and it can't cope. What hardware is yours running on?
That is a common element between us! This is on a Pi Zero W, with a Hifiberry DAC+ Pro HAT. I know the librespot version changed in this release, so maybe that is a factor. I will experiment this weekend with the clean install (I had in-place upgraded from 7.4.1) and I have plenty of larger PI's I can test with to see if the Pi Zero is the root or not.
librespot 0.3 introduced dithering which can be taxing on lower-end hardware. You could try on your Pi Zero with dithering disabled.
Alas turning off dithering had no effect. Nor did dropping the bitrate.
I may mention it on the librespot support forum, see if anyone else over there sees the issue.
I am one of the librespot maintainers. I can't say I've heard of anyone else reporting this. Which isn't to say it can't be an issue because at least you two are obviously encountering it. Hence my interest.
We target the RPi Zero as the lowest-powered device that we support. I don't have one, but one of our members does, and he tested both the dithering and 64-bit sample pipeline on it. So at this point I don't understand what's going on, but think it's worth pursuing.
When you run top, what CPU and RAM usage do you see? What's the current load? Perhaps high I/O usage or blocking? We'd have to investigate further and I can't reproduce.
