[Wine] Getting lowest latency sound?

[Susan Cragin]

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
