Switch "empty" to "no" after you've loaded the server list (in s2 mode) and all S1 servers, even those with players on it, will disappear. When you try to switch it back to "yes" and load the server list again, the empty s1 servers are gone as well.
Ok, I've tested and compared U21 to U20 (WinXP on a MacBook Pro with a Logitech USB headset) and it seems that there are some problems with the new sound system:
No sound in heli cam
With U21 you don't hear any engine sound in the heli cam.
More sound lag
With U20 I can set the sound lag to the lowest possible value (0.10s) and it sounds very smooth. With U21 I get the impression that the sound is delayed for a higher value. It's difficult to say how much, because it's all down to hearing it, but with the direct side by side comparison I'd say that the lag is around 0.20 s now, a lot higher than before.
More stuttering
When driving in a full field with a lot of cars around there are more sound stutters in U21.
Lower sound quality
When reving the engine of e.g. the BF1 in single player mode I get the impression, that some parts of the engine sounds are missing. It's difficult to describe, but I think some sound parts are kicking in after some time delay, in contrast to U20 where you can hear the whole engine sound right from the beginning.
Edit: The horns do work fine here. No difference to U20. Have you tried Shift + H?
Did you guys notice the disconnect problems?
Some other guy did have the same problem and after he changed back to the U version, it did o much better!!!!
There is considerable delay in the sound in U21, most noticeable (I didn't try all cars) with the XFG, and distracting in all cars. It feels like the sound is delayed for several tenths, but some cars are affected a lot more than others. XFG was the worst I experienced, the others were not "terrible", just bad ().
I found there was sound in every (preset) view. I'm currently in the process of obtaining Vista 64-bit RC2 to test the sound and unlocking on that too. From the 1 min tests I did, I didn't notice any connection problems.
The above applies to Athlon XP 64-bit, Win XP Pro 32-bit w/ SP2
when i say 100% i mean that they (just like Vista itself) is beta, and has a few random bugs, but they aren't too bad, although i'm really not a fan of Vista
RTM? I just think they need to write "VISTA IS A BETA - DO NOT USE AS YOUR MAIN OS, IT CAN AND WILL LOOSE ALL YOUR DATA SO DON'T COMPLAIN!" in big letters
Horns work fine, although 1 sounds "different" (although i have ubdated my Chipset drivers which also did my Audio drivers
