Penumbra Collection on Karmic - horrible crackly audio

[BigSilly]

Decided to install my Penumbra Collection on my 64 bit Karmic today, but sadly for some reason there's some audio issues. Basically, it's intermittently giving me this crackly and scratchy type of feedback noise on occasion. I've had a good Google about the place, but to no avail. There are some posts about the issue some years ago on Feisty, but nothing for Karmic. Does anyone here know of a fix for this? I'm using 64 bit Karmic, bit I have ia32libs installed.

Many thanks!

Hey,
had similar issues

There's a beta upgrade for the collection
Patch here - http://rapidshare.com/files/27663361...-1.0.1-2995.sh
thread here - http://www.frictionalgames.com/forum...id=3108&page=1

This patch allows you to specify what audio system is used
OSS works great for me, with none of the crackling that ALSA gave

That's absolutely magic! Thanks very much for posting that up.

EDIT: Bugger. The Rapidshare link is only for premium members, and none of the other links work.

crackly and scratchy type of feedback noise

I suggest --disable-assembly
See thread.

I'm having the same problem except that I bought each game separately earlier (& paid a lot more for them too! :[ ) I downloaded a patch for overture but it didn't help at all
Besides sound there are also new Graphics glitches:
I think I remember the hand being visible most/all of the time. Now it's only visible if it's directly in front of something that it can interact with.
Didn't bother going far, but the snowy ground around the pit by the entrance at the beginning of overture is gone - transparent.

I need a little more explanation. The --disable-assembly thread tells me to:

./configure --disable-assembly in the SDL package

export SDL_AUDIODRIVER=alsa

Um, PLEASE, explain how/where to do that for us noobs. (line by line copy/paste terminal commands)

[Brebs]

The export line goes in ~/.bashrc

I don't use Debian/Ubuntu, so figure out the package recompilation yourself.

[alanwalterthomas]

Ok, Let me write what I have & have not understood before I go do BAD THINGS, & maybe someone can fill in the ?? blanks & correct my mistakes.

I edit ~/.bashrc

?? Then I tack on "export SDL_AUDIODRIVER=alsa" at the end of the file, or anywhere.
I can quickly & easily do that with cat "export SDL_AUDIODRIVER=alsa" >> ~/.bashrc
right?

Then I'll look for some SDL source tarball, unpack it, cd into the folder then do:
./configure --disable-assembly
make -j
make install

I looked at synaptic for a moment & SDL is all over the place. Please let me know exactly what SDL I'm looking for.
I'm sure there are mistakes in the above but that's as far as my knowledge goes.
Help's very welcome.

Edit the libsdl1.2 package.

Look at line 1741 of libsdl1.2_1.2.13-4ubuntu4.diff.gz

+confflags = --prefix=/usr
+confflags += --disable-rpath --enable-dlopen \
+	     --enable-dependency-tracking \
+	     --enable-arts-shared=no --enable-arts=no --enable-alsa-shared=no \
+	     --enable-esd-shared=no --enable-pulseaudio-shared=no
+all_confflags = --disable-video-ggi \
+		--enable-video-aalib --enable-video-directfb \
+		--enable-video-caca
+udeb_confflags = --enable-video-directfb --disable-video-ggi \
+		 --disable-video-svga --disable-video-x11 \
+		 --disable-video-aalib --disable-dga --disable-video-photon \
+		 --disable-video-fbcon --disable-video-ps2gs \
+		 --disable-video-opengl --disable-video-xbios \

+		 --disable-audio --disable-audio-arts --disable-audio-esd \
+		 --disable-audio-oss --disable-audio-nas --disable-audio-alsa \
+		 --disable-pulseaudio

Add --disable-assembly to that, then recompile & install.

[alanwalterthomas]

Huh, that didn't do it.
I downloaded
http://archive.ubuntu.com/ubuntu/poo...3-4ubuntu4.dsc
http://archive.ubuntu.com/ubuntu/poo...13.orig.tar.gz
http://archive.ubuntu.com/ubuntu/poo...buntu4.diff.gz
& put all the .gz contents in the same folder. I edited the .diff file as told. Then
./configure
make
sudo make install

The audio's still crackling.

Now I ran sudo make uninstall. That should put everything back the way it was before right?

Any other ideas?

You need to do the package modification, recompilation and reinstallation "the Debian way" - read up on it.

You have currently got the classic vs Debian installation methods horribly confused.
