JACK's behavior revealed another problem

thank you for your help with JACK. I have cought very basic grip of it,
and stumbled upon another problem. I'm using proprietary ATI drivers,
since with them work cltr-alt-grayplus and ctrl-alt-greyminus to change
screen resolution while maintaining a desktop size, thus providing mi
with very useful, although very basic, magnifier. But now when system
starts, sound devices are given their system names randomly - sometimes
is hw:0 assigned to SB Audigy and hw:2 to HDA ATI HDMI, sometimes is
HW:0 ATI and hw:2 Audigy. I have not recognized the way hw:* devices are
assigned, but when JACK stumbles upon ATI, it refuses to start. So every
time I see JACK's error message, I have to enter setup window and
re-select input and output devices.

And BTW, latency displayed by the Setup dialog is 46.4 msec :(
