The e-mails I received from Darren, helped me with two specific problems.
1. Audio output, Right or Left Channel not working.
2. Dirty Contact in the KeyBed.
If any of you have either of these two issues, maybe this will help.
First you need to know how to take the top off of the Audya and not be afraid to get into it.
With the top open, you'll need to support it upright. If you try to lay it flat it will put stress on the ribbon cables running from the bottom half to the top half of the case.
The wires, I believe 4 of them, that run from the soundcard to the top right pcb is where the audio out problem occur's.
The connector on the top needs to be unplugged and the connector prongs need to be cleaned with Alcohol and a Q-Tip.
About two inches out from that connector, you'll need a wire retainer clip that has a sticky base to stick on the case. A small zip tie is then used to secure the wires to the retaining clip. This prevents the connection from moving, wiggling, vibrating ECT. It forces a tight bond between the male and Female ends of the connector.
2. Dirty contact's in the Key Bed.
If you have this problem, here is a link to a video that will offer some help on cleaning the contact's and contact surface on the PCB.
The video show's work on a Kurzweil, however the contact system is very similar to the Audya. www.youtube.com/watch?v=HdWLspNBOWU
I hope this helps.
