Other notes

Tinkering around with DSi Mode, the DMA and Async and Sound Frequency settings don't make any difference on the noises.

Will you be available for future issues and/or replies?

yes

[DarthPidgey]

did a double check with the new NDS bootstrap version 2.4.0 and verified the rom is a good dump with a matching CRC. Still noise that shouldn't be there.

[RocketRobz]

Have you tried changing the sound/mic frequency to 32khz in TWLMenu++ Settings?

[DarthPidgey]

I already said I tried that in the first post but to double check on the redumped rom and new bootstrap version, it still has noise that shouldn't be there

Sorry, I missed that.

Since it's likely caused by reading the ROM from the SD card, reach to where the noise occurs, then try pressing L+Down+Select to open the in-game menu, and select Reset Game, then reach to where the noise occurs again.
If the noise no longer occurs (or it occurs later in the song), then it confirms the issue is caused by reading the ROM from the SD card.

[DarthPidgey]

The song still has noise after reset, the noise was different and more noticeable where instead of just a popping noise it also made a buzzing noise.

Just chiming in to confirm that this issue also exists on New 3DS XL hardware, played via microSD card, TWLMenu++ v27.13.0 and nds-bootstrap Release v2.4.2. Changing sound freq from 32.73 to 47.61 kHz seemed to reduce the volume of the crackling noise somewhat, but it's still prominent.

[BetaRelics]

I can confirm that this still happens on a New 3DS LL with TWLMenu++ v27.13.2 and nds-bootstrap v2.4.5. Are there any additional things that can be done to help research a fix?
