Re: Persistent names for audio devices.



I agree. In the "normal" shells, you need to use "export" instead of "set"!

Audio messages can be interpreted. Eg.,

Hasty reply. In further use, didn't always work. I removed the PCI
sound card, removed the plastic cover from the sockets on the system
board and connected speakers. Subsequently commands such as this
always work.

set AUDIODEV=plughw:CARD=ICH5,DEV=0 ; play a42.WAV

Are you in csh/tcsh? If you're in a more "normal" shell (bash or zsh),
that set command doesn't do anything useful. Certainly nothing that
would affect the play command.

Even if you're in (t)csh, my understanding is that "set" sets shell
variables, and you need "setenv" to set environment variables (which
could conceivably affect the play command). So, even in (t)csh, I
don't see how your set command is supposed to work.

Other shells... rc? fish? I don't know these. I have no idea what
the set command does in them.
