snd_hda blues

[Bob Johnson]

It is likely that whomever is able to help you will need additional
information. You can get this information by rebooting your system and
selecting "Boot FreeBSD with verbose logging" from the boot menu.
After it boots, use "grep hdac /var/run/dmesg.boot" to extract the
detailed information about your sound system configuration and post it
back to freebsd-questions.

If I have time I will try to look through the info and come up with a
suggestion, but I must warn you in advance that I am unlikely to find
the time in the next few days, so post the info to the list to give
others a chance to look at it.
