Hi, i finally solder my sigma 24+25 for gamma2. It output 5.01V on my test and work fine for gamma
yet after a few minutes of listening, gamma 2 generate some strange noise, i would say hum, and LED of input selector goes off.
Checking the voltage of sigma 25 again gives 1.8V,
Turn off sigma 24/25 for a few minutes and turn it on again, it output 5V again.
But it dropped to 1.8V again after few minutes on Gamma.
Using Gamma only or Gamma + Mcube produce the same result.
I've no idea why this happen, can anyone help?
