Sound freezes after a while on recent OSS versions

Postby r0bert » Sat Mar 29, 2008 9:21 am

Hi,
after my harddisk crashed i was forced to update my system. Now i am experiencing problems with the recent versions of OSS. The sound gets stuck after some time of using it, maybe something like 20 minutes. Applications like audacious stay in the state "oss" and it's no longer possible to unload the module.
I tried the following versions, wich all react the same:
oss-v4.0-build1014-src-bsd
oss-v4.0-build1015-src-bsd
oss-v4.1-build080323-src-bsd
Luckily oss-v4.0-build1013-src-bsd seems to work fine.
Before the crash i was using FreeBSD 7.0RC1 with build1008, this was working fine too.
On build1015 i tried to stream from line-in with darkice, this breaks the module after maybe 3 seconds.

I'm setting spdif.enable to ON, see below for more information:

Thanks in advance, let me know if i can provide more details.

Best regards
Robert

No, build1013 is not workin correctly too.
mplayer was using /dev/dsp0 and audacious /dev/dsp1, mplayer stuck with state "oss" but audacious was still playing :(
Now I'll try the package i found on the FreeBSD FTP (OSS 4.0 (b071011/200802131307))

OK, this version is working as expected, no problems so far.
Still it would be nice if further versions of OSS would work like this, so please don't hesitate to ask if I can provide more information or I should test something.
Thanks!

The source code for builds 1011-1013 is available here:

http://voimakentta.vpalvelin.com/source ... pl.tar.bz2
http://www.fileupyours.com/view/77985/o ... pl.tar.bz2
http://www.4front-tech.com/developer/so ... pl.tar.bz2

(IIRC, OSS was released under BSD during the release of 1012, so we use the GPL version for easy comparison).

If you could test build 1012, compare the files and see what went wrong it would be very nice.

Hi cesium,
Thanks for the reply!
The link to build1011 is not working right now, so I tried to install 1012.
Unfortunately I get some errors I can't fix on my own:

Code: Select all

# cd /usr/src/oss/
# /home/robert/oss/oss-v4.0-build1012-src-gpl/configure
Using the default script
srcdir=/home/robert/oss/oss-v4.0-build1012-src-gpl

FLE /home/robert/oss/oss-v4.0-build1012-src-gpl/buildid.dat->buildid.dat

/home/robert/oss/oss-v4.0-build1012-src-gpl/setup/setupdir.sh: ./srcconf: not found
Source configuration failed

Build ID will become 200803310023
make: don't know how to make dep. Stop
Directory preparation complete.
Build ID will be 1012

I even tried to copy the linux stuff to the missing files, but this is not working. I guess something inside this files has to be altered too, but I'm not experienced enough to fix this.
Any advice?

Try instead:
http://www.4front-tech.com/developer/so ... sd.tar.bz2
http://www.fileupyours.com/view/77985/o ... sd.tar.bz2
http://www.fileupyours.com/view/77985/o ... pl.tar.bz2

The 1012-bsd should compile on FreeBSD. Once this is tested we could compare 1011 and 1012 (or 1012 and 1013), and see what went wrong.

Try to comment this line in "kernel/OS/FreeBSD/wrapper/bsddefs.h" and recompile OSS

Code: Select all

#define USE_SX_LOCK 1

Hi,
I made a package out of 1012, deinstalled the working 1008 package and installed the 1012 package i made. Then OSS froze immediately.
I rebooted and now this version is running for more than 8 hours without problems. I made packages from the other versions and tried them for some minutes too, it seems that I can't provoke the problem on a quick way. I'll try to do some endurance testing with every version now.
On the next version where the problem occurs I'll try Artems hint, thanks for that!
Any idea what information I should save after/while the problem is present?

"Any idea what information I should save after/while the problem is present?"

Sorry, but FreeBSD kernel programming isn't my forte. A core dump will probably be useful.

I'd suggest:
A. Test Artem's patch with a build which is known to fail.
B. Find the earliest version to freeze.
C. Compare that version's code to the version preceeding it, so we can find the regression. This could be untrivial.

P.S. which build is known good 1008 or 1011?

And it froze again :(
After my last post I paused audacious (dsp1), wich was running all the day and used mplayer (dsp0). Now mplayer stuck, but I still can use audacious.
I'll try Artems suggestion as soon as possible, unfortunately I wont have so much time in the next days.

The package that seems to work is named "oss-4.0.b1008_1.tbz", ossinfo returns OSS 4.0 (b071011/200802131307) for it.
http://freebsd.mirrors.tds.net/pub/FreeBSD/ports/i386/packages-7.0-release/kld/oss-4.0.b1008_1.tbz
At least with this package no problems occured so far, and I think this is what I was using before the crash too.

It looks like it is build 1008 which is known good.

So here are sources for builds 1008-1009:

http://www.fileupyours.com/view/77985/o ... pl.tar.bz2
http://www.fileupyours.com/view/77985/o ... pl.tar.bz2

(There wasn't any build 1010).

Thanks for all the code.
I removed the define from version 1015 but this made it worse, now the whole system hangs after a while.
I'll try that with other versions too and I'll try to compile 1009 in the next days.

I have the same problem and the same results, FreeBSD 7.0-RELEASE. :-/
Come to the OSS-IRC channel!
Server: chat.freenode.net
Port: 6667
Channel: #oss
See you there ;)
