[SOLVED] OSS4 troubles (M-audio 5.1)

Following everyone's opinion (http://bbs.archlinux.org/viewtopic.php?id=60614) I decided to try out OSS4. Downloaded the package, sound didn't work (I heard a faint static sound). Googled for a while and found the option to try the oss-mercurial package, and it didn't help (also got that same static sound). I also read the OSS wiki, but it doesn't really have a good troubleshooting section. Tried changing the settings in ossxmix, didn't help (static sound went away when changing to anything other than DMA)
I'm not sure what kind of configs I should paste:

Re: [SOLVED] OSS4 troubles (M-audio 5.1)

Excuse my continued bumping... but I found the problem. More googling led me to people that could not get OSS working who had 4GB of ram. I have 6GB currently in my system, so I pulled 4 gigs out and.... perfect sound. Unfortunately, I'd rather not run my system with 2 gigs of ram when I have 6 to use (not that I come close to running anywhere near 6).

EDIT: SOLVED! Finally. Seems to be a very small bug in osscore.c that prevents anything from >2GB of ram working... Posting here so others may benefit. (found at http://www.gossamer-threads.com/lists/g … er/176346)

Never mind, fixed it. For the record (in case someone has the same 
problem and searches the list), there's a wrong assumption in 
/usr/lib/oss/build/osscore.c: 

if (memlimit < 0x00000000ffffffffLL) 

this needs to be: 

if (memlimit <= 0x00000000ffffffffLL) 

Rebuild with install.sh (same directory) and it should work.

Re: [SOLVED] OSS4 troubles (M-audio 5.1)

I'm very confused about this. OSSv4 runs on my system and I have 4GB of RAM.

Re: [SOLVED] OSS4 troubles (M-audio 5.1)

Not sure what to tell you then Didn't work with my 6 gigs, worked with 2. Made the fix now it works fine.

edit: unless you're running i686? I'm running x86_64

I'm on 64 bit and I did nothing special. Although, I've run into at least one application that can't see OSSv4 at all, and another that seems like it can't (possible user error). It would be nice if they're related; I prefer OSSv4 but I'm currently using ALSA for compatibility. I'll try it out.

--EDIT--

I rebuilt with the line corrected and it changed nothing. It plays sound like before, ekiga through ptlib still can't see it, I still can't seem to get ossrecord to do anything... Nothing changed for me.
