Here are my findings about recent radio-like noise mixins I get to hear. I'm
using yet another application, using DirectSound, so it seems. wine-1.1.10
makes no difference vs. 1.1.9.
You can download the 47MB demo of The Nations / Die Völker II at
http://www.jowood.com/?lang=de&site=2&gameid=voelker2&iid=Demo

I'm using Ubuntu Intrepid with
+ latest updates as of today,
+ pulseaudio 0.9.10-2ubuntu9
+ Intel Corporation 82801FB/FBM/FR/FW/FRW (ICH6 Family) AC'97 Audio Controller
(rev 03)

Using or not (pactl exit) pulseaudio makes no difference to the sound glitches
I hear.

Using OSS works fine.

Much to my surprise, I also found out that using ALSA with:
+ driver emulation
+ HW accel. emul. (otherwise a hissing sound is heard / mixed in)
+ at 8bit, 22050Hz
works fine with 1.1.10 in Ubuntu Intrepid, with or without pulseaudio.
Using different settings in winecfg (e.g. 44100/16) produces various noise
mixins.
But is this really using ALSA? WINEDEBUG=+dsalsa comes out empty in this case.

Using ALSA instead of OSS prevents the bug where the PCM mixer mutes from
showing up.
