In reply to nathanlanham, I tried your suggestion (remove alsa, install
OSS driver v.4.0), still no sound.
Here is the output of ossinfo:

If I go into Sound Preferences, select OSS and click the Test button
for playback, I get:
audiotestsrc wave=sine freq=512 ! audioconvert ! audioresample !
gconfaudiosink: Could not open resource for writing.
