DecTalk Interrupting Sound?

[Hart Larry]

Quite hard to explain well in a subject-line, but when I am playing any audio 
in my sound-card useing alsa, if I do any reading, even such as typing a time 
command, the sound breaks up.  I am writing here as I sure don't know the 
cause?  The Dec-Talk is a U S B unit--and should have nothing to do with my 
sound-card.
First I orriginally thought it was a bandwidth issue, where I would read on 
shellworld while listening to streams, but then I went to a console not 
online--and proved that it has more to do with either the Dec-Talk.  Could 
their be something similar to IRQ settings in DOS, where there would be a 
conflict?  I suppose the other interesting thing to try would be running 
another combination with ORCA, so we would iliminate speakup as a facture.
I also at times am also ripping streams while listening in another console, but 
I have not tested to see if the ripped item brokeup.
I certainly want to rip lots of Election coverage--and want to keep up with my 
mail.  Lately I just leave the keyboard alone while ripping anything I am also 
playing through the sound-card.
I think this is an mp3blaster
Thanks so much in advance for any solutions
