In the first occurrence you didn't notice that the 70% volume was output
volume, while the 100% volume was microphone volume.

The second occurrence shows a real jump, however (lines 18014-18015):

D: [pulseaudio] protocol-native.c: Client kmix changes volume of sink
alsa_output.pci-0000_08_06.0.analog-stereo.
D: [pulseaudio] sink.c: The reference volume of sink
alsa_output.pci-0000_08_06.0.analog-stereo changed from front-left: 26208 / 
40% / -23,88 dB,   front-right: 26208 /  40% / -23,88 dB to front-left: 65536 /
100% / 0,00 dB,   front-right: 65536 / 100% / 0,00 dB.

The log looks like kmix sets the 100%, but of course it may be that PulseAudio
is misinterpreting the data that kmix sends. One way to debug this would be to
modify pa_context_set_sink_volume_by_index() so that it logs at the client side
the parameters that kmix gives.
