hdaudioctl graph - how to use?

[Mayuresh <mayuresh%acm.org@localhost>]

I am stuck with no audio on NetBSD 5.1 for intel hd audio identified as
below:

#  dmesg | grep -i audio
hdaudio0 at pci0 dev 27 function 0: HD Audio Controller
hdaudio0: interrupting at ioapic0 pin 21
hdafg0 at hdaudio0 vendor 0x8384 product 0x76A0 nid 0x01 (firmware
configuration)
audio0 at hdafg0: full duplex, playback, capture, independent
hdvsmfg at hdaudio0 vendor 0x14F1 product 0x2C06 nid 0x02 not configured
audio1 at pad0: half duplex, playback, capture


Headphones do work, though not the speakers.

Is hdaudio module as of 5.1 capable of working with Intel hd audio
hardware described above?

Are there any tweaks needed with hdaudioctl etc to get it work?

I'm also curious about the graph I could produce with hdaudioctl. Just
don't know how to make use of it. Is there any tutorial on whether this
graph could help get audio work etc?


As a last resort I am trying to build NetBSD Current to see whether
hdaudio works with current. But not quite used to it. Getting stuck with
config tool itself not getting built.

Is there any way I can build latest hdaudio code for 5.1 kernel?

Mayuresh.
