I've also posted this to linuxmusicians.com as well, but I thought I'd post here too as this seems to be LMMS specific - although it could be Carla, but the guys there are probably way too busy to respond to my weird problems.
I'm recording LMMS live (a number of a reasons why, not least of which the Stochas sequencer won't render out notes in LMMS for some reason, which is also unknown to the developers).
I'm getting the occasional loud pop or crackle randomly during playback. I'm assuming that it's the CPU, but it could be something else too which is why I'm asking here. Unfortunately, I'm not going for the lofi sound
I have set the LMMS buffer to its very maximum.
I'm resisting using any synths that might be heavier on the processor (Vital, Surge, Odin2)
i have set the CPU governor to performance on all 8 cores.
I'm running two instances of Stochas in Carla within LMMS, six instances of Synth1 (obviously using the Wine bridge), one instance of Decent Sampler and two instances of Valhalla Supermassive (again, wine bridge).
The machine I'm running it on is a little "mature", but should still be quite capable:
HP z240 Workstation; 7th Generation core i7; 16GB RAM; NVMe SSD with plenty of space.
The audio is going through an nvidia K620 card (I realise this probably makes no difference but I thought I'd mention it).
I'm running stock Kubuntu 22.04 minimal install (compositor is OFF) with nothing else installed but LMMS and associated plugins/synths/effects. ALL background services are switched off.
When playing back, the CPU is running somewhere between 30%-40%
I'm recording through sox, but the popping happens whether I'm recording or not.
Does anyone have any ideas if there's anything I can do to fix this? This is driving me insane. Thousands of gamers livestream stuff way more processor intensive than this and often on lesser hardware. What am I do wrong?
