[alsa-devel] Gina 3g and Echomixer issue
Hey guys,
I work in an auditory neuroscience research lab, and we are using a PCI Gina 3g to communicate with a Fireface 800 over ADAT.
My issue is this, 1) each time I reboot the system the digital mode is set to Coaxial digital, rather than ADAT, and I must set it after each reboot. Is there a way to make this setting persist through reboot, or perhaps a parameter that can be set when the kernel module is loaded to force ADAT?
2) The first time I switch from Coaxial digital to ADAT upon a reboot, I consistently get a loud squeeling sound coming from my studio monitors. I don't think this is the intended behaviuor, and it makes me worried when switching into ADAT mode. Granted, after switching the first time to ADAT, I can switch between coaxial digital and ADAT without the squeeling happeneing, it is just that first time after the reboot.
Thanks for the help guys. The Gina 3g, even though it is an old audio device, is still our most reliable sound card. We have tried many others with horrible success, and most other ADAT capable PCI/PCIe sound cards are far too expensive, and don't have robust Linux support. However, if you guys have a good reccomendation of an ADAT capable PCIe sound card with full Linux support, please let me know.

In theory, all mixer controls can be saved over reboots. (Some boot script should call "alsactl store"/"alsactl restore"). Does this happen for other controls?
As a last resort, you could change that control separately:
amixer set "Digital mode Switch" "ADAT Optical"
