Recently added SOtM sms 200 ultra neo with their LPS stack to pair with Gustard R26, connected via USB.
Bought a LHY Ock2 clock too, which goes to both SOtM and R26.

What all inputs in R26 can utilise the external clock?
I emailed Gustard support they replied back saying all.

In order to connect my Shanling ET3 (cd transport) to my Gustard R26 via i2s I just finished a custom vlds cable according the below pin-outs to find out that dsd material is now played and recognized correctly (by R26) but when I play pcm it is recognized as being pcm (by R26) but I only hear noise.

ET3(pin) / label / Gustard(pin)
1 / data/dsdr- / 9
3 / data/dsdr+ / 7
7 / lrck/dsdl- / 3
9 / lrck/dsdl+ / 1
15 / f_mute / 16 (nc)
16 / f_dsd / 15

Any ideas what I am doing wrong (does anyone have a cable or wiring schematic that plays both pcm and dsd correctly between ET3 and R26) ?
