Need help configuring upsd, sound and logo saver on freebsd 8.0

[Manish Jain]

Hello All,

I recently installed FreeBSD 8.0 on my amd64 system attached to an APC 
UPS via USB and a RealTek HDA onboard soundcard. I chose 'logo' as the 
screensaver during installation, and put snd_hda_load="YES" in 
/boot/loader.conf and upsd_enable="YES" in /etc/rc.conf.

On booting, the sound driver gets loaded successfully and the APC UPS is 
also detected (although there is no mention of the UPS in the output of 
dmesg). I have the following problems :

1) There is no sound. AFAIK, there is a sysctl parameter to be tuned for 
setting the correct audio channel (in my case hdac1), but I have 
forgotten the parameter name. Can someone please remind me ?

2) upsd complains of inappropriate ioctl no matter which USB device node 
I set in /usr/local/etc/upsd.conf. How can I set the device name 
correctly so that the OS can shut itself down properly on extended power 
failure ?

3) For my console saver ('logo'), I get the following error message at 
boot-time :

module_register_init: MOD_LOAD (logo_saver, 0xffffffff81044010, 0) error 19


Happy New Year and Thanks for any help
