Solid State Logic SSL2 - problems while playback

Post by dpavlushko »

Recently I've bought an SSL2 usb interface. It works out of the box, only one problem it make clicks (every ~5 sec) while playing test file:

Code: Select all

> sox -V -r 192000 -n -b 24 -c 2 sin2-192kk.wav synth 30 sin 24
> play 192k.wav
I tested different buffer settings with no luck. Similar interface EVO4 and SoundBlusterX G6 works on that computer.
Also, I tested the interface on Mac and Windows - all good.

Any idea how to fix the issue, what else can I check/change?

Here is some alsa info:

Did you try different sampling rates too?

I guess it requires implicit feedback quirk, just like SSL2+

Thank you so much!

I added this line, rebuild the kernel and it works:

case USB_ID(0x31e9, 0x0002): /* Solid State Logic SSL2+ */
+case USB_ID(0x31e9, 0x0001): /* Solid State Logic SSL2 */

I confirm SSL2+ works 100% after kernel rebuilding with that line added.
Distro: AVlinux 2020.05
Kernel: 5.6.17-rt10-avl1

So happy, thank you very much :D
