Re: [Qemu-devel] [PATCH] PC speaker emulation (fixed point)

[Joachim Henke]

Ok, these are really strong arguments. Thanks a lot for your  
interesting statements! I'll do some testing on square waves and will  
post an updated patch, as I am also not totally satisfied with the  
current sound myself.

Sincerely
Jo.
