This has already been reported as
Issue 3026, but I might as well list it here, too.
This buzzing in SSBB is really similar to the buzzing you reported in DKCR, except it's more prevalent.
Yeah

, Resident Evil The Darkside Chronicles sound is working fine now

.
I tested r7338x64 mamario both HLE and LLE sound is working fine now (finally) thanks
Anyone confirms this:
Issue 2190 fixed
http://code.google.com/p/dolphin-emu/issues/detail?id=2190
Any work / fix for Resident Evil 4 Wii Edition.
I tested r7338, music still does not work well.
Edit:This TREAD should be an "Important Threads".
Resident evil remake (GC) still has an issue with both (HLE LLE).
With HLE there is no music in save room, and with LLE there is but after 2-3 sec there is a 50% frame drop and ofc, music starts to sound choppy.
Same happens with Resident evil 0 when you encounter zombies.
Any chance of having a "Fix"for BGM loops in RE4, some dev is looking for this?
Some INFO about DPSHLE and LLE:
BGM Loops in HLE on files of type:, brstm, ras, snd, aix, adx, tpl, tpl.lz,files, work perfectly and all these files ,the music files are "separated"(It has many files,adx,brstm....)
BGM Loops in HLE, But sometimes not start to play the bgm: "dsp"files(MP1,MP2E), works when it wants in HLE.
BGM don't loops in HLE on: "ast"files(MKDD,SMG)
BGM not play on HLE on: "exa"files.(007FRWL)
BGM don't loops on BOTH on :"sbb"files(RE4)
RE4 uses a different method, it has all the songs in a certain file "sbb"[
attachment=6051][
attachment=6052] that is why, dolphin can't loop, dolphin don't has support to loop many bgms on a single file like sbb, it has many bgms inside.
Hope this information can help on something.
I also troubled with RE4 BGM Loops,hope developer see what hyperspeed said and fix it quickly.
Thanks.
