i noticed in mostly naomi 2 games, for example soul surfers and beach spikers,

sometimes the in game gets way louder than it needs to be and overlaps the sound effects, seems to be a on and off basis

volume warning btw

In Sega Driving Simulator the steering wheel is miswired to the volume control, so steering to the left cranks up sounds to the max while steering right turns it silent. Apparently some analogue game inputs got mixed up. This may be a related issue.

This appears to be a regression due to 7cc77b1.

Fixed on master

[TheCoolPup]

Thank you

There seems to be an issue where the sound is sometimes biased towards the right channel.

Set the region to Japan and launch Soul Surfer. There is a noise when the controls explanation screen is displayed for the second time. There is an audio glitch in the right channel on the hard ranking screen immediately after the fourth controls explanation screen.

From the hard ranking screen: soulsurf.zip

Audio glitches should be fixed on master. This was due to audio samples being played before there are copied to audio RAM. So data is now transferred in chunks at regular intervals, similarly to what's done with the GDROM. However there is a significant risk of regression with all naomi (1/2) and atomiswave games.

Thanks for fixing it. The audio glitches on the Soul Surfer controls and hard ranking screen are now fixed. Unfortunately the audio glitches on Beach Spikers replays etc still seem to happen occasionally.

Unfortunately I can't seem to reproduce the issue on Beach Spikers. I haven't played for hours but no issue with the sound during replays.

[TheCoolPup]

did some testing and the audio issues seem to be gone, thank you for fixing them flyinghead. :)

[TheCoolPup]

can confirm the issue still happens on beach spikers

If only I could get a savestate to reproduce this audio glitch at will...

[TheCoolPup]

Can’t right now but later if it pops up again, I’ll send a savestate

[flyinghead]

The thing is: I need a savestate before the audio glitch happens, which is almost impossible since it doesn't seem to happen that often.
