\_ SMTP quoth George Toft on 4/19/2002 08:55 as having spake thusly:
\_
\_ How can I tell if an application is using the sound card? I'm writing
\_ a script that needs to play a sound, but only if the sound card is not
\_ currently being used. What I'm doing right now is:
\_
\_ IN_USE=`lsof | grep dsp`
\_
\_ Which works, but I know lsof can impose a performance hit. Any ideas?
See if there's a cautionary file lock on /dev/dsp? I don't remember
if I was getting file-lock errors or perm errors when I 'fixed' this.
If the box is running esd, you *might* be able to grok the output of
esdctl serverinfo or esdctl allinfo into something meaningful?
Good question.
