Alsamixer can’t turn on ADC high or Output Mu

I can’t set Alsamixer to match the recommended settings.  Specifically I can’t turn the ADC high filter or the Output Mu.  I have no idea why.  

Receive audio is good, but not consistently and sometimes changes from radio output to unknown sounds.  

Transmit it audio is almost no existent, not enough to drive K3 

I am using RX in and TX audio separate cables. 

What am I missing here?

Thanks to all again,

I have included an alsamixer screenshot:
