Linux World of Goo: no sound : (

[naikon]

Hi, I have gotton World of Goo working under
freebsd 7.1 working recently using linux_base-fc6.
I can't for the life of me get sound working though.

when I select the dsp driver(oss) in the config and run
the game, everything works, but the debug info simply
tells me that the oss driver was selected, and that audio not
initialised. Is it possible to emulate ALSA under FreeBSD?

I have tried other games like darwinia and uplink demos from
the ports tree, and the same problem persists.

I have installed most linux related sound libraries but alas no
use. Are there any sysctls values to be set?

Please enlighten me, I would love to game with sound under
this excellent operating system:)

Can you try this?
sysctl hw.snd.compat_linux_mmap=1

Is it possible to emulate ALSA under FreeBSD?
Fortunelly, no.

Linux programs should be able to use OSS though. Perhaps you're missing some library? I had a similar issue not to long ago with the linux-flashplayer. Turns out it wanted a different version of openssl then the one I had installed. Oddly enough everything worked except sound.

Have a look with:

/compat/linux/bin/sh /compat/linux/usr/bin/ldd /path/to/linux/executable

[naikon]

Can you try this?
sysctl hw.snd.compat_linux_mmap=1

It just returns with:

"sysctl: unknown oid'hw.snd.compat_linux_mmap'

Maybe another kernel compilation is in order?

[naikon]

I have ldd'd the linux binary, and they are all
linked fine. There is no reference to openssl in the manual
or the library requirments.

Man, this is stumping me:(

[SirDice]

Is wasn't saying openssl was the problem, just that a missing library prevented everything else from loading.

But if they're all there then this isn't the problem..

Is audio working in native fbsd applications?

[naikon]

Yes, sound works in native applications, even in the
linux flashplayer9.

I wonder if this particular app doesent support sound
under freebsd emualation. It's not like there is official
support from the devs. Only ut2003-demo has sound, and also
exhibits grpahical artifacts unlike world World of Goo.

Ut2003 is the only port that does have sound though.

I have linux-doom3, linux-enemyterritory, linux-quake4, and rtcw and they all have sound.
Some years ago the audio stopped but I've found that with the mentioned sysctl the sound was working again.
I use linux_base-fc-4 and compat.linux.osrelease=2.4.2, because, when linux_base-fc-6 was committed, I've tested it but it was working worse.
I've also tested linux_base-f8 but it's even worse because I think that something is not working properky with the linux part of the nvidia-driver.
I also get a message like: FATAL: kernel too old and a core dump installing the nvidia-driver with 2.6.16.

What is strange is the message about the sysctl, that's what I have
$ sysctl hw.snd.compat_linux_mmap
hw.snd.compat_linux_mmap: 1
Also, in /usr/ports/UPDATING you can find a note about the fact that compat.linux.osrelease=2.6.16 is not fully supported in 7.x.

Can you try with linux_base-fc-4 ?

[naikon]

I passed the above sysctl parameters in the latest RELEASE 7.2.
Everything works fine now with the linux_base overridden to 2.6*

Thanks again for the help folks:e
