I used wget to download

$ aplay -t au english.au
Playing Sparc Audio 'english.au' : Mu-Law, Rate 8000 Hz, Mono
I did not hear anything
# dmesg | grep -i snd
returns nothing
# dmesg | grep -i alsa
returns nothing
btw, I posted most of this and alot more in my original
message dated Monday, 20th August:
subject: sound prob Ensoniq ES1371 on Fedora 7
I pasted most of the contents of scsconfig.log.
I deleted parts I thought had nothing to do with
sound.
Thank you very much for responding to my email!
