No, I'm not. I assume you're referring to the mount option, which doesn't appear in my /etc/fstab. Also `findmnt -O discard` gives no output but `findmnt -O nodiscard` does. Is that the correct way to check this?
pylkko wrote:But now I reread your post and see that you do say in it that multichannel audio in Audacity is really behaving in odd ways. Are the audio files that you are editing on the HDD or the SSD?
The files are on the HDD. I should point out that the out-of-sync error I described happens quite rarely. More often Audacity freezes in the same way as Mirage, i.e. during playback (even if there are only two tracks and one is muted), it stops refreshing the window for several seconds, while the audio keeps playing as usual.

I'm sorry if I haven't been very clear. The conditions I've reported are not "stress" conditions, just ordinary everyday tasks. I haven't tried to run any actual stress tests yet.

I believe I am. The system automatically updates the package cache daily and notifies me if there are upgradable packages. These days there are several almost every day.
If I run `sudo apt-get update` and `sudo apt-get upgrade` manually, the latter says:
Code: Select all
0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.

I'm glad you asked. I wouldn't be at all surprised if the file was somehow messed up.

It's basically inherited from jessie. I noticed only just now that the first pair of deb/deb-src lines contains "main non-free contrib" while in the rest of them, the order of the components is "main contrib non-free". That inconsistency must have been there for years. I changed the order of the first lines to match the others and ran `sudo apt-get update` and `sudo apt-get upgrade` again, but the ordering doesn't seem to make a difference. Not that I expected any.
My /etc/apt/sources.list.d/ is empty.

I guess I should do just that, once I have a little more spare time.
Thanks for all the feedback, again.
