[Bug 20277] New: Elder Scrolls: Oblivion slowdown and loss of background music since introduction of mpg123

http://bugs.winehq.org/show_bug.cgi?id=20277

Summary: Elder Scrolls: Oblivion slowdown and loss of
                    background music since introduction of mpg123
           Product: Wine
           Version: 1.1.29
          Platform: PC
               URL: http://appdb.winehq.org/objectManager.php?sClass=versi
                    on&iId=7506
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: msacm32
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

/*
> From application comments/ on behalf of JFM Rivera.

Also - missing winemp3.acm category for the bug, so assigning to msacm32.
*/

Up to wine 1.1.28 the game works normally, however, testing the newer two
versions (1.1.29 and 1.1.30) produces the following:

1. Incredible game slowdown (like a slideshow). The game slows down to the
point that it takes several attempts to register a key press.

2. Loss of background music (though ambient sounds come through) using ALSA
output (same as the issue noted on the post below)

Using OSS output I get no sound, but the game is at normal speed. Using OSS and
launching the game with "padsp wine" results in ambient sounds returning, but
the slowdown is back. No setting I've tried so far has resulted in restoring
the background music.

Under wine 1.1.28 sound works (ALSA) and the game runs at full speed.

Workaround:
Take winemp3.acm.so from /usr/lib/wine on a 1.1.28 install, and put it in
/usr/lib/wine on a 1.1.29 install.

What distro? How was the Wine installed?

Sorry, I cannot reproduce this.

I'm using Ubuntu 9.04 32-bit, Wine 1.1.31 and Alsa/Pulseaudio over Creative
Labs SB Audigy soundcard. Wine installed from .deb package.

Will ask JFM Rivera for more details and try soundcard which doesn't do HW
mixing.

AppDB user gersen who can see the issue too,  reports that the 1.1.29 affected
package was Slackware package from Sourceforge.

Following messages can be seen in wine output:
fixme:quartz:ACMWrapper_ConnectInput acmStreamOpen returned 512

I'm also experiencing issues I suspect are due to winemp3.acm.so missing in
newer packages.

Running Kubuntu 9.10 amd64 here.

Manually extracting the file winemp3.acm.so from a 1.1.28 package, and placing
it in /usr/lib32/wine fixed the issue.

Wine's winemp3.acm.so require libmpg123 installed on your system. Did you do
that?

I'm unable to reproduce the bug on Ubuntu 9.10 both with HW sound mixing (SB
Audigy) over ALSA backend and with SW mixing by pulseaudio over simpler
soundcard.

Using packages from http://wine.budgetdedicated.com
Using both old wineprefix and clean new wineprefix.

Please try to satisfy all Wine dependencies by installing required packages and
install the game in clean wineprefix to see if the problem appears again.

Probaly the bug is either caused by a missing libmpg123 library, or by
a packager who intentionally removed mp3 support.

In either case it's invalid.

You should be able to reproduce the issue by doing the following:

Remove /usr/lib32/wine/winemp3.acm.so

Reinstall your wine package.

Performance will become horrible in oblivion, like 2 fps.

I hadn't considered the possibility that it may have been intentionally removed
by the packager. Quite possible I suppose.

I am on Ubuntu Karmic 32bit (ATI Radeon 2600XT+fglrx) and I'm experiencing the
very same issues (music not playing + extreme slowdowns). I tried versions
1.1.31 (from the Ubuntu repos) and the latest 1.1.34 from launchpad with the
same results.
I then extracted the winemp3.acm.so from an old 1.1.28 Jaunty-Build and put it
in /usr/lib/wine which fixed music playback but the extreme slowdowns still
make the game unplayble.

Oh, I forgot to mention: On 1.1.34 Oblivion is _completely_ unusable for me as
it fails to load old savegames (it hangs with the progress bar at about 1/3)
and quits to the desktop.

I can confirm this. For some reason there is no winemp3.acm.so in v 1.33 and
1.35, that I have installed in playonlinux shell for wine. Manually copying
winemp3.acm.so to ~/.PlayOnLinux/WineVersions/1.1.35/usr/lib/wine fixed the
issue with slowdown and loss of background music.

Created an attachment (id=25426)
 --> (http://bugs.winehq.org/attachment.cgi?id=25426)
Dirty patch to fix the background music and sound in Morrowind, Oblivion and
possibly others

Experiencing the same issue with Morrowind, I investigated the cause of the bug
in HEAD (31f3fa0773bafe0f495292fd978597f4dbc2d17a). The attached patch should
work in any wine version since the introduction of libmpg123 though.

I found that the title music worked when issuing the following command:
  WINEDEBUG=+mpeg3 wine Morrowind

Upon further investigation I found an extra call to mpg123_getformat done only
when TRACE was activated that made the sound work. This patch just run that
function even when TRACE isn't activated. This probably isn't the real fix but
I'm looking for some feedback before I look further into it.

It fixes the issue with Morrowind, I assume it's the same for Oblivion, though
tell me if it doesn't fix Oblivion and I'll fill a separate report. It might
also fix bug 21091.

Please apply this patch (or run the above command) and tell me if it works for
you.

(Incidentally this patch also fixed my mouse going slow every few seconds.)

OK reading the documentation for libmpg123 it appears my patch is the correct
behavior expected.

"Message: Output format will be different on next call. Note that some
libmpg123 versions between 1.4.3 and 1.8.0 insist on you calling
mpg123_getformat() after getting this message code. Newer verisons behave like
advertised: You have the chance to call mpg123_getformat(), but you can also
just continue decoding and get your data."

( http://www.mpg123.de/api/group__mpg123__error.shtml )

People on Ubuntu Karmic have 1.7.3 so that means mpg123_getformat *must* be
called for them after getting that message code, otherwise the mp3 simply can't
be read.

On newer versions a call to mpg123_getformat is essentially harmless according
to the documentation, so there's no reasons not to call it.

This bug persists for me with wine 1.1.38.
I do not have /usr/lib/winemp3.acm.so.
The WINEDEBUG=+mpeg3 trick did not work for me.
Oblivion is completely unplayable.

I am using wine on a 64bit Gentoo system, so this might also be a
gentoo-specific bug. I will report this on the Gentoo bugtracker later.
Perhaps you could tell me whether it is normal that /usr/lib/winemp3.acm.so is
missing or not, so I can tell the Gentoo developers?

Presumably they're disabling mp3 support, possibly because of patent issues.
Check is the '--without-mpg123' configure option is being used.

Yes, thank you, I should have checked that before.
Actually, they are disabling mp3 support on amd64 currently because of bug
#20042.
Sorry for spamming in this bug report.

Even when using winemp3.acm.so from an earlier version I still get the
following error in the terminal.

ALSA lib ../../../src/pcm/pcm.c:7075:(snd_pcm_recover) underrun occured

Occurs mainly when:

loading a game from the main menu
load screen after fast travel
load screen after exit to main menu (occurs twice)

This is wine 1.1.36 (Ubuntu 8.04 AMD64) from budgetdedicated
All sounds will play but underrun still occurs.

With 1.1.38 from budgetdedicated there is only voices and music, no other
sound.

Bug 20118 may be a duplicate.
