            Bug ID: 50161
           Summary: Garbled sound in Unigine Superposition
           Product: Wine-staging
           Version: 5.22
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown

When running Unigine Superposition benchmark, the sound is all garbled -
"White-noise". This did NOT happen with <=wine-5.21 or <=wine-staging-5.21.

I pinpointed this to the staging-patchset: msvcrt-Math_Precision

If you add ONLY this patchset to wine-5.22, you will have this bug. I suspect
it has something to do with msvcrt now being built as PE lib maybe? 

However, i was not able to do a debuglog with: WINEDEBUG="+msvcrt" cos that
just caused this:
002c:trace:msvcrt:DllMain stack overflow 1968 bytes in thread 002c addr
0x7f84d4c31c25 stack 0x120850 (0x120000-0x121000-0x320000)

0044:trace:msvcrt:DllMain stack overflow 1968 bytes in thread 0044 addr
0x7ff7e91d9c25 stack 0x120850 (0x120000-0x121000-0x320000)
004c:trace:msvcrt:DllMain stack overflow 1776 bytes in thread 004c addr
0x7fb80858a80c stack 0x120910 (0x120000-0x121000-0x220000)

Not sure what else i can do to provide any meaningful log from this.
