[Wii] Audio Crackling and Buzzing when Playing Content.

Is there an existing issue for this?

• This is a bug in RetroArch frontend
• I have searched the existing issues

Description

Audio Artifacting observed on Retroarch [Wii] when loading games on some cores (Snes9x, 2005 Plus)

also referencing ticket 16219 raised in February.

Expected behavior

content starts without audio artifacts (Crackling, Buzzing, Blown out Speaker Sound) referencing healthy build 1.8.7.7

Steps to reproduce the bug

1. Start Retroarch Wii
2. Default Settings
3. Start Content
4. Load Rom - Tested: Megaman X, X2, Contra 3 (is present in all roms tested)
5. Choose Snes 9x, Snes 9x 2005 Plus
6. Run
7. Game Starts with audio artifacts (Crackling, Buzzing, Blown out Speaker Sound)
8. Rolling back to build 1.8.7.7 resolves the audio artifacting. (no impact to standalone emulator Snes9x either)
   Changing Core Settings/Retroarch Settings does not make it better or worse.

Start by reproducing the audio artifacts on Wii with RetroArch 1.19.1 or a nightly build, then compare behavior with healthy build 1.8.7.7 using Snes9x and Snes9x 2005 Plus. Investigate changes between those builds affecting frontend audio or core loading; done means tested content starts without crackling, buzzing, or blown-out sound.
