had sound working, updated machine now lost sound

[Antonio Olivares]

Dear folks,

I have a machine recently updated to 8.4-RELEASE-p3 and ports tree
updated from 05/27 to Friday of last week. I had sound, but now have
lost sound.  I had the usual snd_hda_ in /boot/loader.conf

When I send
# cat /dev/sndstat > /dev/pcm0

I get:

/dev/pcm0: Operation not supported.
root at grullahighschool:~ # cat /dev/random > /dev/dsp0
^C

When I do last command cat /dev/random > /dev/dsp0 I hear the sound,
how can I redirect it to have sound.  The headphones used to work, but
now also have no sound.

Thanks for any advice and suggestions to fix this issue.

Best Regards,


Antonio
