Not necessary the seq=0, as it can be multichannel output, but in this 
case -- yes.

Unfortunately I am almost run out of ideas. Neither Linux nor audio/oss 
seems have specific code for your system. That makes me think that 
problem is in some different basic assumptions in the drivers. But that 
doesn't give any hint to find it out.

You may try to play with setting different levels of ivref/ovref 
voltages via hint.hdaa.0.config tunable. I haven't even seen it 
affecting power amplifier, but who knows...
