Hi,
   Iam using qemu 0.13.0.whenever Iam playing any audio(wav or mp3 file)
using ffplay there is alot of jittring sound or distorted audio very much in
case of mp3 files.so Iam trying to figure out what could be the problem..so
anybody can give me a clue whats going wrong..Iam using kernel(linux2.6.33).
I thought of using DMA. but in kernel or in qemu I dont find register
SYS_DMAPSR(DMA peripheral MAP register) at  base address 0x1000064.so I want
to know whether DMA is supported here in qemu for realview boards.
Plz let me know as soon as possible..

--Thanks
Asim

Hi Asim,

please follow these instructions to properly report your bug: 
http://wiki.qemu.org/Contribute/ReportABug

Especially using an up-to-date version is important, as it's likely that this 
bug has been fixed in meantime (0.14.0 is the current stable).

With regards,
Jan
