SB16 Emulation not working with OS/2

Hello,

the SB16 emulation of VirtualBox 6.x. does not work correctly with OS/2. The sound card is visible and can be accessed, but playing any sound stops prematurely after half a second or even less. Sounds shorted than this time are not played at all.

Attached is a log with setextradata <Name-of-VM> "VBoxInternal2/Audio/Debug/Enabled" "true"

Does this happen with all 6.x.x releases, i.e. 6.0.0, 6.0.2, 6.0.4 and 6.0.6?
What if you revert to 5.2.28?

Hello,

I did not use version 6.0.0, but 6.0.2 and 6.0.4 had the same problem.

With version 5.2.28 sound playback is not 100% perfect, but it is /much/ better than in 6.x. While 6.x only plays a small part from the beginning of each sound, playback is nearly complete with 5.2.28 cutting just a (very) small part at the end.

Can you please try with 6.0.0? It may seem trivial, but if the developers know that this is a 6.x issue and not a 6.0.0 -> 6.0.2 issue, it helps a lot...

I've tried version 6.0.0 today and it has the same problem as versions 6.0.2 to 6.0.6.

JFTR: This issue was present until version 6.1.22 and was fixed with version 6.1.24.

Thanks for the confirmation.

Given this closure, now is a good time to lock this old topic I think.
