The channel map specifies which channel goes to which
physical output.
ok. i thought the values were a range, because the controls makes it look like that. maybe these ought to be changed.

Simple mixer control 'Master',0
Mono: Playback 37 [59%] [-39.00dB] [on]
That is pretty low.
i just use the Master switch as my main volume control. i have PCM and other switches at 0 dB.
just to clarify the problem, it's not that i can't get it loud enough. it's that it's relatively quite low compared to Windows. in Windows, i barely have to up the volume to get the same audible level. the speakers' physical nob is the same for both instances.
Node 0x11 [Audio Selector] wcaps 0x30010d: Stereo Amp-Out Amp-Out caps: ofs=0x17, nsteps=0x1f, stepsize=0x05, mute=1 Amp-Out vals: [0x17 0x17] Connection: 1 0x03
when loopback mixing is enabled, the current driver remove the previous "PCM playback volume" and set the amp at 0dB which is 12 dB lower than the previous version
