Linux Mint 21. AMD Ryzen 5 5500. 32GB RAM. AMD Radeon 5700 XT. Soundblaster Audigy RX PCIe.
I never had this issue with my old computer (Mint 19, built-in audio), but on the new one, I installed Audigy last night (2.4.2 from Mint’s repository) and since then, there’s a constantly increasing lag between video and audio. It only goes away once I kill pulseaudio, but then it comes back and keeps getting longer and longer.
constantly increasing lag between video and audio.
Who’s ahead? Writing a complaint is something of an art forum. We assume the sound is late, but you never say that.
Delays can be a little magic. If you have a constant speed error, it will appear that the error is getting worse and worse, but in fact, it’s just that the longer you wait, the further apart the two events are.
Do you have a sample rate error? As a bad example, if the picture is running at 44100 and the sound is presenting at 48000, the sound will be running slow and sync will appear to get worse and worse, but isn’t really. That’s just what a speed error looks like.
You could have something broken and the sound service is occasionally dropping bits. That usually throws an error; that’s pretty serious, but not always.
Did the timeshift and restored the computer to a pre-audacity state and the lag (audio after video) was gone, but only until I tested the appimage version of audacity. About 10 minutes after having audacity open, the lag reappeared and kept increasing.
Closing audacity and restarting pulseaudio reset the lag (no lag), but it reappeared even after having closed audacity.
Last night I rebooted the computer and haven’t opened audacity, and there’s no lag so far.
So far my only working theory is that installing audacity didn’t break anything, but once I use the program, it does break something.
My plan today is to stick with ocenaudio for my needs and see if the lag reappears.
