ALC268 Audio - Can anyone help?

[Cheops]

Hi,

 

I have an Acer 7720g Laptop with the Realtek ACL268.

 

I have tried implementing my pin config data and also the pathmap items but I am not getting any audio from my speakers, I am getting very confused.

 

On my hardware I have 2 normal speakers on top node 0x15 and a bass sub speaker on node 0x16 both nodes need to be playing at the same time to produce quality sound. On Ubuntu I have to do the following command to enable the bottom speaker to enable it.

 

hda-verb 0x16 SET_AMP 0xb000

 

I would be very grateful if someone could please check my AppleHDA.kext for discrepencies.

 

I have attached what I think is needed for this including linux codex dump, graph, windows verbs.

 

Any help much appreciated.

 

Cheops.
