<pre>Hi,
I have a Thinkpad X250 (i7 from Broadwell generation) on Ultradock (that has a
DP MST switch) connected to Yamaha RX-V475. At least once per minute the sound
stops shortly for less than a second and then continues normally. This is very
annoying and basically renders MST audio support useless, but I did not
investigate further so far. The graphical output does _not_ have this problem
and continues working normally. The Yamaha av-receiver has a small segment
display, which changes it text, but it changes back too fast for me to read. I
guess it notices, that the audio stream broke up. I don't see anything useful
in dmesg (this is without any special debug flags in kernel parameters).
