    'PCM' is not present in DAC+ Standard on my Raspberry Pi 2, using Debian jessie. One should use 'Digital' instead.

    I can confirm that this KB is not relevant with the DAC+ Pro. It should be:

    $ amixer sset 'Analogue Playback Boost' 0%
    $ amixer sset 'Digital' 100%

    100% seems to be 0 db and not 96%:
    Front Left: Playback 207 [100%] [0.00dB] [on]
    Front Right: Playback 207 [100%] [0.00dB] [on]

    Might be worth to update the KB :)

    I'm wondering if this article is written confusingly or if I am the one with a misunderstanding... To get "the full output volume without clipping", the only thing is not to have any Playback Boost, right? The other setting 'PCM' or 'Digital' is not relevant, but the article makes it sound like you need to have that set to 96% to avoid clipping...
