I run a HP nx9005 notebook with a docking station (port replicator) F808b.
The nx9005 comes with an ALI 5451 soundchip.
Linux kernel is 2.4.23 with alsa-driver 1.0.0rc2, snd-ali5451.
lspci -v
00:06.0 Multimedia audio controller: ALi Corporation M5451 PCI AC-Link
Controlle
r Audio Device (rev 02)
Subsystem: Hewlett-Packard Company: Unknown device 0024
Flags: bus master, medium devsel, latency 64, IRQ 5
I/O ports at 8400 [size=256]
Memory at d0005000 (32-bit, non-prefetchable) [size=4K]
Capabilities: [dc] Power Management version 2
Everything works well - as far as I have tested - with one exception: there is
no signal at the headphone-out on the docking station.
Headphone-out on the notebook is o.k.
Test with oss-free driver: same result.
Test with oss-commercial driver: works.
Test with WinXP: works.
It seems that the port on the docking station is fully functional, but the
driver doesn't recognizes it.
My knowledge in this area is somewhat restricted - gently spoken.
I don't even know how to run further diagnostics.
Any help is greatly appreciated.
Regards,
Andreas Mahling
