There is an issue where after sending or receiving a fax with FaxSTF, the sound will stop working after the PowerBook has been brought out of sleep if FaxSTF is set to answer calls.
Workarounds:
- Set FaxSTF to "Answer on never" in the Fax Browser settings.
- After the issue occurs, put the PowerBook to sleep and then bring it out of sleep once again. The audio will start working again and will continue to work until the PowerBook has restarted and the problematic scenario occurs again.
It is normal behavior for the sound input to change to Internal Modem when coming out of sleep if FaxSTF is set to answer calls.
Note: Macintosh PowerBook G3 Series computers should not be confused with Macintosh PowerBook G3 computers. Though the names are similar, there are significant differences. To visually identify which type of computer you have, close the display and inspect the display case. A Macintosh PowerBook G3 has a small, six-color Apple logo on the display case. A Macintosh PowerBook G3 Series computer has a large Apple logo on the display case that is not six-colored.
