Re: UA-25, only one program can access the device at a time?

Just

defaults.pcm.card UA25

on one line by itself??

If I replace my current asound.conf with that line I get these errors when restarting alsa:
tony@o_0 ~ $ sudo /etc/init.d/alsasound restart

The default configuration would use dmix, but your configuration file
overrides this.

Try instead the following:

defaults.pcm.card UA25
