Hmm.. my T420 does not have SPDIF and could possibly be broken by this
change.

        wfg ~% amixer controls
        numid=2,iface=MIXER,name='Master Playback Switch'
        numid=1,iface=MIXER,name='Master Playback Volume'
        numid=23,iface=MIXER,name='PCM Playback Volume'
        numid=5,iface=MIXER,name='Capture Switch'
        numid=4,iface=MIXER,name='Capture Volume'
        numid=8,iface=MIXER,name='IEC958 Playback Con Mask'
        numid=13,iface=MIXER,name='IEC958 Playback Con Mask',index=1
        numid=18,iface=MIXER,name='IEC958 Playback Con Mask',index=2
        numid=9,iface=MIXER,name='IEC958 Playback Pro Mask'
        numid=14,iface=MIXER,name='IEC958 Playback Pro Mask',index=1
        numid=19,iface=MIXER,name='IEC958 Playback Pro Mask',index=2

==>     numid=10,iface=MIXER,name='IEC958 Playback Default'
==>     numid=15,iface=MIXER,name='IEC958 Playback Default',index=1
==>     numid=20,iface=MIXER,name='IEC958 Playback Default',index=2

        numid=11,iface=MIXER,name='IEC958 Playback Switch'

        numid=17,iface=PCM,name='ELD',device=7
