Missinformation city again.
Threaded video is not a speedhack, its - threaded processing of the video variety.
THA SOUND BEIN IMPROVED -
is such an incredible display of daftness, that I'd want to punch everyone in the face for asking others in a "so what would you say - makes the sound improved the best" way - if I hadn't done that already in this thread kind of.
I'll do it once more -
1. Its not our fault that you notice a game not running full speed on sound first. If thats the issue, dont blame "tha sound"
2. If a game runs slow, the sound emulation actually can run as fast as it is supposed to, because sound and gameplay are supposed to sync up. So then its not even the sound emulations fault - its just that the game runs slow. The sound emulation probably even could run faster - but you'd not want an out of sync game.
3. When using threaded video, there could be audio sync issues resulting from that, which also isnt the fault of "tha sound". But those then mostly should be sync issues not distortion issues.
4. If sound emulation actually was "slow" this could be helped "a bit" by increasing audio latency. The thing is - THIS HARDLY EVER IS THE CASE with pcsxrearmed on the switch. I dont know what worked for you on the PC with that dolphin emulator - but increasing audio latency shouldnt do much in this case. Unless in some case it does, and I look like a propper mug here. Increasing audio latency could be seen as something of an undesired "speedhack" because it is.
5. If you are unable to identify any of those scenarios, dont try to fix that with "but what would you do" and "should I try different app". Thats an insult.

Also.
Enable threaded video, try to set the audio driver to switch_thread, and play with frame duping and vsync on and off - are only the first four things to do to get improvements in pcsx rearmed.
If you only take the first of those things (threaded video) and forget about the rest - because you cant follow multi part arguments - that on you as well.
The reason why I am this animated, and would like to hit you in the face, when I see people doing this is, that we've explained this probably 10 times in three days in this thread. And there was still enough place for morons to feeeeel that you had to explain it to them personally - just because they were so special.
Now that some tome has gone by - it might be harder to find those posts. But the idea was, that people would pick up on them, and be able to explain that stuff to others, so some of us dont have to do that for the 20th time. But now the result is, that people read the first bullet point, started replicating it - and forgot about the five others.

Also they are still impossibly daft, when it comes to identifying whats causing issues.
If f.e. it should be the case, that "your PC is too slow to run a game", and you end up complaining to your "fix my PC friend" that you hope the developers will fix the games sound soon, he'll think that you are a proper moron. Keep that in mind.
Of course I don't expect people to be able to find the toggle for the fps display in retroarch, but still. Complaining about "bad sound emulation", when you are not even making sure that your game has a chance at running full speed - is one of those things.
Knowing, that sound will sound distorted, if a game runs at 52 fps, but is supposed to run at 60 is also part of that. Only if you can rule that out, can you complain about "bad sound emulation".
Also you know what fixes slow emulation speed? And lets you use Beetle PSX with 8x the original render resolution? Buy a better PC. Complaining that you'll hope it will be fixed soon? Not on the short list of proper solutions.
Also I wrote the first part before. Probably more elequently than I did right now, and with more thought. Look it up if you want to. I remember putting stuff about frame skipping in there as well.
