OK, applying this patch breaks the build:

./.libs/libpulsecore-5.0.so: undefined reference to 
`pa_device_port_find_best'

I suppose the patch is not intended to be applied against the 5.0 release.

However, since I now know that the bug was with saving the volumes, not 
with restoring them, I fixed this by simply "rm -r ~/.pulse". Now the 
volume is always 100% on startup.

Thanks for you help :-)
