           Summary: dsound buffer underrun lockup stutter .. again...
           Product: Wine
           Version: CVS
          Platform: Other
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: major
          Priority: P2
         Component: wine-directx
        AssignedTo: wine-bugs at winehq.org
        ReportedBy: spamalltheway at bigfoot.com


Wine (CVS 2004-12-21)

Game tried:
Heroes of Might and Magic 3 / III Complete (Exe version v4.0)

Files:
- Log of full dsound,wave output
- Log of only the default error output
- lspci dump of the used hardware
- ver_linux output

No full log since it was hitting 2.4 meg lines after only 6 seconds runtime ;-)



Tried sound output methods + "results":
- ALSA:
In the intro the sound output consists of something sounding like a very _fast_
reset being done on the soundcard every .1 to .2 seconds (accompanied by tons of
messages along the lines of:

fixme:dsound:DSOUND_MixOne problem with underrun detection (mixlen=8832 <
primary_done=8900)
err:dsound:DSOUND_MixOne underrun on sound buffer 0x403f9d30

).

The sound starts playing in the Mainmenu afterwards.
When ever you put only a little additional stress on the CPU like eg. moving the
mouse cursor (graphical cursor in HoMM 3) or doing a "ps ax" in a shell window
repeatedly)  the sound stutters _badly_, accompanied by messages along the lines of:

fixme:dsound:DSOUND_MixOne problem with underrun detection (mixlen=2302 <
primary_done=4782)
err:dsound:DSOUND_MixOne underrun on sound buffer 0x403f9d30

At this point they are mostly of the first type though.

Creating additional stress for 1.5 seconds or above often makes the sound gui
crash (no sound, but the rest of Wine and the game are still running).
Sometimes whole Wine decends into a dead lock without _any_ error messages being
printed (=> pkill -9 wine*).

In case of deadlock the usual message occurs ;-) :
err:ntdll:RtlpWaitForCriticalSection section 0x403f86f4 "?" wait timed out in
thread 000c, blocked by 0009, retrying (60 sec)


- OSS:  No sound at all with hardwareacceleration != Emulation, only a black
screen instead of the loading game with hardacceleration == Emulation

- Jack: A little sound, although stuttering more badly (mostly due to jackd
creating a little stress to the cpu all the time, just like moving your mouse in
the ALSA 'chapter').

- ArtS: Same as jack, but stuttering without needing any additional stress on
the CPU (maybe this is again CPU load  since artsd is surely creating a little
when having clients).


Changing the settings in dsound to incredibly high/low values didn't help at all
(except for creating a constant stutter when making the buffer size too small).



Software:
Wine is the CVS version as of 2004-12-21.
Linux 2.6.8.1
Debian Sarge / Unstable (if related at all)


Hardware:
CPU: Pentium 4 Celeron 2.4Ghz
For the rest see lspci output.
