It was in fact a hardware problem. With my darn mouse, a Mad Catz RAT 7.

Since that's the model of mouse that I use, I thought I'd pipe in and say that I've not encountered the sort of issues you've described either either of the ones I've had so far

Cheeseness;  thank you for the valuable input!  I'm working on all of this, and will report back when I have more information.

No worries - wish I had a bit more time to dive into it. If you want to grab me on Steam/IRC (I can normally be found in #steamlug on freenode)/whatever I can try to work with you to try to further track stuff down when I'm around.


Also awesome to hear that Wadjet have brought somebody onboard and are looking to keep them contributing back

What type of audio do you have? Any other audio issues on your system?

I'm running a Creative Audigy 2 Platinum Ex. Never really had any issues beyond a couple of Wine games (like Rage and Orcs Must Die 2) having this crackly audio thing from time to time (quitting and running pulseaudio -k has always sorted it out). My partner encounters it when playing Dead Island as well. I think she's running onboard audio (looks to be an intel chipset).

The issue I've been encountering can best be described as crackly audio (I'll see if I can get a recording of an example during the week).

I got around to uploading to YouTube my instances of it:

Yep, that's it.

Am I to understand, then, that restarting Pulse no longer eliminates the current incarnation of your audio corruption?

With your build, pulseaudio -k doesn't fix it on my Wheezy VM. With my build, it doesn't fix it on my desktop
In all other cases a pulseaudio -k dies help (until it happens again).

This makes me wonder whether there's something I could be doing during my build process (I'm pretty much just using the ags+libraries script), or whether the bundled deps themselves are causing issues.

Runs nicely on my F17 install. 0.5 sec worth of crackly sound when starting the title I'm packaging, but it comes right every time. It also seems to recover happily from switching focus after a second or so of crackly audio.

On my Wheezy VM, I get crackly audio no matter what I try (the same issues I'd been experiencing with my own build). I don't have a proper install to test on at the moment though.

This is good info, thanks.  It's probably fairly instructive that the glitch traverses distros, but follows Pulseaudio.  I can reproduce this at will on my test setup.  All that's left is the hard part (figuring out how to properly debug the problem).

It's also interesting to note that my Wheezy VM is running from a MacBook Air rather than my F17 desktop.

Hey, Cheese, what's up? 

Small world, hey?

I'm packaging an AGS title for Linux for a friend of mine

Ooh, exciting!  Another title!

If all goes well, it'll be two titles

What are you running?  What is the nature of your Pulse glitches?

I'm currently running Fedora 17 32 bit on my main desktop and building stuff from a 64 bit Wheezy VM.

The issue I've been encountering can best be described as crackly audio (I'll see if I can get a recording of an example during the week). I had previously encountered sped up audio, but I haven't seen that for a while (and can't recall what I did to trigger it). I've had similar crackly audio issues with a number of titles in Wine which normally go away with a pulseaudio -k, and of course in the Gemini Rue beta.

We have no reason to think that A5 will do anything to help this whatsoever, as it doesn't seem like an A4/Pulseaudio problem specifically (nobody is reporting this issue on other A4 Linux games)... Recently, I've had some personal challenges, and frustratingly, my work there has not progressed as I've wanted.  I am committed to working on it, though.

Yeah, OK. I'd gotten the wrong impression from your post in the second Gemini Rue beta thread. I can see now that what you were saying about the issue was unrelated to the A5 migration.

Totally with you on the frustration front. We'd first started talking about packaging the project I'm helping out with on back in December, but due to a number of unforseen and unrelated circumstances, we had a number of false starts and it's taken till now to actually move forward with it. Don't feel bad - we do what we can.

I also read a few pages back that people had been working on config generation scripts (and trying to get ahold of source for a UI?). I had planned to make something quick and dirty using Zenity, but if there's other stuff in the works, I might be able to throw a little time at helping things move forward.

Well, Electroshokker built this:  http://www.adventuregamestudio.co.uk/forums/index.php?topic=37968.msg501047#msg501047

...which apparently worked really well, and properly configured DIGIMID for ALSA (one bug report came from a Slackware user who was Pulse-free... setting up the proper DIGIMID index in the acsetup.cfg fixed his wagon).  I'm fairly content to continue porting forward the util, once code appears.

Ah, so that's what was being discussed. Already sounds a lot more sophisticated than the quick hack I was looking at putting together.

scottchiefbaker has a simple generator script in-place for the Gemini Rue beta which may be sufficient until we have a GUI.  Perhaps he'll share it with you?

Could be worth taking a peek at. If you're keen, get in touch, scottchiefbaker

Thusly, I would be ever so grateful if you would give these a test-drive on Wheezy for me (we don't support Squeeze, right?).

Hi fellow Linux shaped devpersons.

I'm packaging an AGS title for Linux for a friend of mine (who'd prefer that the title wasn't publicly announced for Linux prematurely), and I've been encountering audio issues with Pulse (which I've seen mention of in this thread) with my builds. I'd like to resolve these before we start broader testing and would consider an interim workaround if anybody's got any ideas (using padsp to force alsa doesn't help, and I haven't had much luck with any cfg settings either).

It sounds like the resolution for this that's currently being pursued is the Allegro5 port which Crimson Wizard and s_d (?) have been talking about. I have a tiny bit of allegro experience, but I don't feel like I have enough familiarity with how AGS' innards work to try tracking this down, and I don't have enough availability to sink my teeth into the Allegro5 porting effort. I can certainly offer encouragement though

So far I've been using Allegro4.4. I've noticed that some are talking about 4.2 - are there any know issues with 4.4 and AGS that I might have missed?
