Please unblock package gsequencer
There are some important bug-fixes available to gsequencer-0.7.122.
The fixes provide improvements to application stability. It might
look like there are many lines in the debdiff but the changes
are rather small und they use proven concepts.
(include/attach the debdiff against the package in testing)

+Description: AgsClearBuffer fixes data-race causing distorted audio output
+ resulting in useless audio output. Introduced due to low-latency sync
+ strategy for ALSA audio output and alsa MIDI input. Might end in application
+ crash and is required by immediate sync strategy.
+ This patch includes the Makefile.am fixes to use the new object and its
+ functions.

+Description: This patch is considered critical since it fixes the beginning
+ of the data-race. It has a strong relation with soundcard output. Since
+ the start of threads has some uncertainity about when it is ready. It
+ has a need for 2 tics to be ready and not only 1.
+ Note this is a work-around, better would be add 1 tic to tic_delay field as
+ it's in sync. But it's not evident when it happens.
