Audio ceases, tracks or tracks and effects #369

Description

@SNESaholic

Hello, I just received my Saroo and set up a bunch of games, and have observed an odd behavior that I haven't seen others posting about. The initial audio track and sounds will play and sound great - but subsequent sounds often won't load. The behavior is very consistent, and will happen in exactly the same way at the same place every time. It happens in several games.

As an example, I will use Cotton Boomerang, because it is small in size and known to work well on Saroo, as far as I can tell. On my setup it will play all sounds perfectly for the intro video, for the start screen, for the character select screen... and then nothing. No more sound at all. Only the sound is affected. My Saturn works just fine with games on disc. Because the behavior is not at all random, audio quality is wonderful when it starts up, and it always happens at a transition, it seems quite likely to be a software issue.

Background info:
64gb MBR FAT32 sd card
Games in merged .bin/.cue format (also tried split)
1.66 blue-pcb Saroo
0.9 firmware
VA0 US Saturn
Yes, I did cover the B7 pin on the daughter board and it solved all the random audio issues
Yes, I did disassemble it and check all sides of the board for corrosion / cap issues
Yes, I made sure contact is good between Saroo and Saturn w/ multimeter

My thanks for any suggestions you may offer! I would be glad to try any recommended settings etc.
