Topic: HDSP 9652 & Ferrofish A16, no sync
I'm not sure if this is a Linux related issue, but I thought to be safe I would post in here.
I just picked up a second-hand HDSP 9652 and Ferrofish A16 (AD/DA conv) that I'm using with a new Arch Linux build.
I was able to get hdspconf installed from the asla-tools AUR package.
It seems to recognise my card correctly.
I have two ADAT channels of the 9652 connected to the A16. The A16 reports that it is receiving signal okay on both ADAT A and B, but no sync lock on either.
I have the A16 set to receive clock over ADAT with the sample rate set to 44.1, which is what I've set it to in hdspconf.
In hdspconf I've confirmed that the System Clock mode is Master.
hdspconf also does not report sync lock on either of the ADAT channels.
To check something wasn't faulty with the card I looped ADAT 1 out of the 9652 to ADAT 1 in on the card (a tip I found while seaching these forums for a solution). In this case hdspconf reported sync on ADAT 1.. So it seems the card is working fine.
What should be my next steps to troubleshoot this?
I am brand-new to both of these devices, so it could be the case that I've overlooked something very simple.
I've installed the linux-rt kernel to rule out some issue with timings there.
I've also looped the ADAT out of the Ferrofish to its own in, and it reported sync lock in that case. So that seems to rule out a fault of both devices and cables.
Also, if I run a speaker-test, I can see all the channels light up on the hdspmixer. So internally things seem to be functioning as intended.
Still, no luck with the 9652 and A16 locking onto eachother however..
