Audio glitches

[Rabittelong]

Bought my saroo from Timeharvest Store updated to firm v0.4 and most of the games start fine but then the sound glitches at random with buzzes and wrong sounds playing, I'm at Japanese VA0 Saturn the weird thing is not all the games are affected by this issue.

It may be that a clock circuit on the VA0\VA0.5\VA0.8 motherboard does not have shielding protection.It is an early motherboard design problem.

Might need to try the motherboard:
Can you take apart a Sega Saturn yourself?
Are you proficient in using a soldering iron?

Sorry no I don't have any soldering skill.

I can recommend using tape on on the smal motherboard method. Took about 10 min and fully working. CD ROM not working but audio works from saroo and sound fx without glitches. Tested today.

I have some soldering skills and have had the same issue with sound. What can be done to solve the issue with soldering?

I don't think you have to soldiering. Use the trick with tape... if you need optical drive cove just 1 of the pins on the cdrom small motherboard. If drive is not necessary use big piece of tape and cover following pins

You can try removing C47 cap but someone reported it didn't change anything.

Yeah I did the tape trick on the CD drive pin in the end and the Saroo is working fine now with no problems. Just wondered if there was a solution that means I can still use my CD drive if needed.

Tape pin 7 and drive should work Wysłano z programu Outlook dla systemu Android<https://aka.ms/AAb9ysg>

If only the B7 PIN is processed, the CD drive will not be affected. You can still use CD

[jerbearwright]

I can confirm this works also. I was having the same issues with a MK-80000 US VA0 as recommended I taped off pin 7 on the small board and all the problems seem to be gone!

I have exact issue with sound glitches on va0, is there a video turorial or pictures for taping B7 PIN or schematics?
no soldering things.

[Backloggaming]

Is there a chance that the sound glitch can be fixed by future firmware update(s)? I’m using version 1 Japanese Saturn. And I noticed a pattern while playing Asuka 120%. The sound glitches comes on and off depending on what state /game stage you are on. It seems affecting the SFX memory channel only and not the BGM.
