Hello!   
Today I have received my assembled sammichSID. Unfortunatelly, it is not working as supposed to work.  
There are 2 major symptoms:  
1. Knob and buttons are not working at all (not even one). 
2. When I launch Ableton Live and start playing MIDI notes through sammichSID I can hear only mono buzz despite Lead Patch selected (it is automatically selected after turning on the device). Of course my cable routing is proper. I can see LED blinking (received MIDI notes), but my sound card/headphones gives me only barely audible buzz.   
More information: 
1. I can flash the device with the latest firmware available without any problems, 
2. I can load a sound bank (v2_vintage_bank.syx) via MB SIDV2 Editor v0.5, 
3. LCD and LEDs are working normally (tested with sammichCSTest.hex, Ableton and MOS Studio), 
4. After reading some other posts I have double-checked that: 
- heat-sink is not touching anything, 
- RN1-RN4 are in correct positions.  
Here are the photos - maybe I'm missing something:

Any ideas what might have gone wrong?  
Any help is appreciated.
