I tried to investigate the preamplifier chip further but run into another bug.
I'm not able to access the SMBus. When I execute "modprobe i2c-i801", the following appears in the kernel log:

[...] ACPI Warning: SystemIO range 0x000000000000f040-0x000000000000f05f conflicts with OpRegion 0x000000000000f040-0x000000000000f04f (\_SB_.PCI0.SBUS.SMBI) (20140214/utaddress-258)
[...] ACPI: If an ACPI driver is available for this device, you should use it instead of the native driver

I tried mainline kernel 3.15.6 but the problem is still present. Only found this: http://askubuntu.com/questions/449102/ubuntu-12-04-loading-i801-i2c-driver
