I used a 10 pin IDC header and ribbon cable, then isolated the required wires and soldered to DB9 plug. I only have three wires connected at the DB9 end.
Thanks spzzzzkt! I'll add a db9 plug to my parts list-I have a feeling I must have several old cables in my attic I can repurpose.

Hi,

with M2Tech USB-I2S there occurs switching noise when changing track clock too.
Soomtimes it takes the Dac takes up to two seconds to lock on.
IIrc the M2Tech supplies a status bit or a clock dependant signal that could be used to switch a DAC much faster, so that it locks in less a ms.
Maybe other USB-I2S converters provide for a similar feature that may be used here?

is there any way to fix i2s as a default connection and disable others to eliminate lock on time. For sure it must be valid even after power off and on.

Or maybe Soren you can release variant firmware for spesific usages/purposes.

Connect INP_SLCT0 and INP_SLCT1 pins to GND, see post #901.

It will always take a little time to switch sample rates with the reclocking FIFO. I will for next release check on the timings and optimize, should cut it down to below a second.

But it's always a compromise, it really need enough time to measure the incoming clock to set the initial oscillator frequency.

As I'm not getting any plop's here with my diyinhk usb interface I will procure an amanero for testing, the plops need to, and will be eliminated....

Just to ensure it's not your software, have you tried a different audio player ?
