I think the issue is solved by now. Here is how: I put out my old Creative SoundBlaster Live! soundcard and activated my onboard sound (Realtek 7.1 HD stuff). I then just installed the according drivers and since then, I can join any mp game I want. BIG LOSS however: recording volume of the onboard sound sucks major ass. I can do what I want, I can't boost my mic volume or anything. Maybe I have to buy a new soundcard or something -.-

http://community.bistudio.com/wiki/ArmA:_Startup_Parameters Thanks man, I'll check that out as soon as I get home. Still at work now

So I now reinstalled the game completely ( German DVD, 1.50 Full, 1.50 to 1.80) and the error is still the same.

Exact same problem here man, replacing the OpenAL32.dll however did NOT do the trick for me. I am unable to play multiplayer STILL! My friends have no problems playing... its so weird.

It really has to be said that I cannot even terminate the program. I tried ctrl+alt+del to terminate it, nothing would help except for pressing the reboot button. I even tried to shutdown windows but it CANNOT terminate arma.exe, it stays alive no matter what I try. It happened again today after playing a LAN match over hamachi. I clicked on the "disconnect" button and it hung itself... the only solution was a hardware reset.

hmmkay, thanks for the input. But isn't it really strange how I can't even close down the program, regardless of how many times I'm hammering ctrl+alt+del, alt+f4 and so forth?

Ok this bug elaborated a bit, so I'm editing now to summarize measures taken and things that occurred to me. My shit: Q6600 4x 2.4GHz (Untouched) ATi Radeon X1950XT 2GB Corsair PC800 RAM WinXP Pro SP2 completely up to date MSI P35/G33 Neo-F Series Realtek Onboard Sound ArmA German DVD Version 1.08 (Non-Hotfix, because I've tried that before). Of course this is a legit copy. Symptom: The computer locks up *completely* when I try to join an Multiplayergame or when I try to host one. Also, the sound is 'flickering' really awkward. It sounds like its echoing a bit or something. Hard to describe. Measures taken: - Turned off my firewall - Replaced my OpenAL32.dll in windows - Reinstalled completely and went without the 1.08 Hotfix - I played around with sound-settings - Hammered ctrl+alt+del, alt+f4, ctrl+esc, alt+tab Status: SOLVED. I put away my old Creative soundcard and now use my Realtek onboard card/drivers. Things working fine now. Its not a satisfactory solution though, so I really recommend the devs should have a look at this.
