I know you are trying to be helpful, and I thank you for that. However, I am only posting here to keep the thread alive.
As a retired Linux/Unix Systems Programmer, I have extensive experience with Linux. I have been using Linux since shortly after Slackware was released. If there were an error, I would have found it. I am not your typical user, and my system is not typical. I can provide any info Jonas might need. However, I doubt Jonas could duplicate my system. For example, I have 48GB of RAM, 19 TB of active storage, 28 TB of offline storage for backups, and a few TB of network-shared storage.
BTW, my music is on a local attached (SATA) hard drive.
Strawberry worked fine for years, and then the buffering thing started while I was using Fedora. I later switched to Linux Mint LMDE 22.1 because I support people who have Linux Mint and only support one Fedora system.
