[0.13.15][Twinsen] Opened machine sound being sped up

[AGuymzx]

I may have found the cause of the sound bug surrounding machines' working sound being pitched up, previously addressed here: viewtopic.php?f=29&t=14817

It seems vehicles are somehow responsible for pitch-shifting working sounds, due to vehicles pitch-shifting their own 'working' sound during transit.
In order to reproduce this, get into a vehicle (a car, for example), speed up to the point it's sound starts pitching up, and proceed to open the vehicle's inventory. Close the inventory, get out of the vehicle, and then open any running machine's inventory. You'll find every machine from this point on has it's sound pitch-shifted.
You can make this stop by simply getting back into the vehicle, open its inventory while standing still (so the sound has not been pitched up yet), and then getting out.

Below is a video demonstrating this procedure:

Could it be due to an in-intended piece of functionality, where an inventory being opened with a pitch-shifted working sound will carry this pitch over to the next inventory opened? While vehicles can cope with this just fine and therefore re-adjust this pitch based on their speed, regular machines do not, and round to the highest possible pitch while the pitch is not the default.

This may not be the sole cause for this sound problem, however. This is only a way I found to reliably reproduce the effect. I'm not entirely sure yet about other ways to cause this sound bug to occur.

I'm running Win10 64-bit, with an on-board Realtec sound card.

Thank you for the report, and welcome to the forum

I have managed to confirm the issue

Thanks for the clear steps, was able to reproduce the issue.
I had a good laugh listening to inserters and bets at full pitch.
