HP Pavilion DV6 & sound?

[openbsdguy]

No sound, but everything else seems to be working.

I have a Pavilion dv6 (Canadian model), where the display and wifi (athn driver) work perfectly. Only 3.5Gigs are recognized, but after reading the earlier threads - no worries.

• I'm wondering if perhaps the audio might work better if I ran i386?

• Also wondering what the benefits of running amd64, as opposed to i386 - (i.e. only 3.5 Gigs are seen)...

Cheers,
Guy
