OpenAL Audio Update: Use 1.0.2553 Patch instead!

[Urkle]

This patch is no longer applicable and SHOULD NOT BE USED!

Please use the official 1.0.2553 update for linux located:
http://support.frictionalgames.com/entry/65/

I have an update to OpenAL that I would like users to test. Use this update if you encounter crackly sound or other sound artifacts. This can be applied over Penumbra: Overture Episode 1 Demo OR Full Version. If you have the full version (you do don't you??) Please make sure you install the 1.0.679 patch.

This patch will install a libopenal.so.1.0.0 into the Penumbra "lib" directory. This will NOT overwrite the old libopenal.so.0.0.0. It will only update the symbolic link libopenal.so.0 to point to the new file.

If you need to revert back to the old openal lib run this from within the Penumbra Overture install directory.

Code: (Select All)

cd libs
ln -sf libopenal.so.0.0.0 libopenal.so.0
cd -

And to use the new lib again run

Code: (Select All)

cd libs
ln -sf libopenal.so.1.0.0 libopenal.so.0
cd -

Please put any feedback you have about this patch to this thread.

I tried the replacement lib. Started a new game, but when the initial boat map loaded there was a fairly loud screeching noise, I think it was one of the game SFX but messed up. I could still hear other audio like the boat's horn, and interestingly enough the menu/intro all sounded fine, but I didn't bother with it and reverted back to the original lib.

I use an AC97 integrated audio chipset.

I can confirm that "screeching sound".
All sounds ingame (not menu and intro) sound crappy. Just like the bitrate was reduced or something was badly encoded.

I also use an AC97 compatible sound card (but not an integrated one).

I've not bought the game yet, and I didn't download this patch.
I've always got creepy sound with OpenAL before I make a little modification in /etc/openalrc :
For KDE users ( I'm not, so, I'm not sure it works ) :

Code: (Select All)

(define devices '(artsd))
(define alsa-out-device "default")

For GNOME users :

Code: (Select All)

(define devices '(esd))
(define alsa-out-device "default")

[Linux.Blue]

after using this patch, I get no sound at all

Penumbra crashes on startup after using this patch. I had to revert to the libopenal.so.0.0.0 library. I use Ubuntu Gutsy Gibbon. The last message I see in the hpa.log was: "Trying to open audio device".

The game also crashes on my setup. I'm running 64-bit Linux and running an ldd on the library gives:

Code: (Select All)

[gianni@Blackhawk lib]$ ldd libopenal.so.1.0.0
        linux-gate.so.1 =>  (0xffffe000)
        libm.so.6 => /lib/libm.so.6 (0xf7f45000)
        libpthread.so.0 => /lib/libpthread.so.0 (0xf7f2d000)
        libdl.so.2 => /lib/libdl.so.2 (0xf7f28000)
        libc.so.6 => /lib/libc.so.6 (0xf7dd4000)
        /lib/ld-linux.so.2 (0x56555000)

All deps are covered, and I'm not sure what is causing the crash. I ran the game with ulimit -c unlimit so that it would generate a core dump, which I'm trying to attach (hopefully it does attach this time)

I don't seem able to attach the core dump file, maybe because it is a .bz2 file? (it also is of 4.3Mb down from an original of over 42Mb!!)

[Urkle]

Follow the directions in this post on how to get a backtrace. Then just attach the output.

Also, please include your hpl.log file as well from the run where it crashed.

I think that what you need to know and want to see is the following:

Code: (Select All)

Core was generated by `./penumbra.bin'.

Hope that helps.

Edit
Forgot the hpl.log file... DONE

Just to see if might also help, here are the contents of my /etc/openalrc file:

Code: (Select All)

;;(define devices '(alsa native))

;; uncomment this to output via the 2nd soundcard
;;(define alsa-device "plughw:2,0")

Hi,

I tried the patch, and it just ended in making the game segfault at startup.

I use Mandriva 2007.1 Spring with a 64 bits environment and a 2.6.17-15mdv kernel.
