wine users - Nov 2008 - Getting lowest latency sound?

I have been trying to get lowest-latency sound (with highest fidelity) to use
with Dragon NaturallySpeaking.

I have Jaunty and the latest RT kernel, which I know has problems for many
applications but works fine to run DNS. (It will not, however, install the
program nor train it.)

I set up real-time audio access as follows:
sudo su -c 'echo @audio - rtprio 99 >> /etc/security/limits.conf'
sudo su -c 'echo @audio - nice -20 >> /etc/security/limits.conf'
sudo su -c 'echo @audio - memlock 1500000 >>
/etc/security/limits.conf'

So as I understand it, rtprio is the correct #, nice is the lowest possible, and
I memlocked half my RAM.

In winecfg, I have audio set to 48000 default sample rate. 

I have an internal hda-intel soundcard (bad but better since alsa upgraded to
1.0.18). I also have a SoundBlaster X-Fi that doesn't work yet, but I'm
waiting with my fingers crossed, since SoundBlaster open-sourced some of the
code this month.

Any fairly simple suggestions?
How about a chrt command?

Thanks. Susan

Hi Susan,

You should try using windows applications that use ASIO and use the Wine ASIO
driver, WINEASIO.

Do you mean that my program, Dragon NaturallySpeaking, has to depend on ASIO
when it runs in Windows? Dragon is really the only choice in speech recognition
software.
