  • Thread-topic: AudioServerPlugin: resynchronization

Hello,

Asking again because I'm still stuck on this one ;-(

I would like to ask the HAL to resynchronize it's PLL on certain condition (i.e. when the external clock has changed).
To do so, I increment the outSeed value returned by GetZeroTimeStamp but it looks like the HAL just ignores the seed.

At this point, the only way I find to "force" the HAL to resynchronize it's PLL is to change the sampling rate.

How I have to do?


Note: I noticed that inIOCycleInfo.mIOCycleCounter is always zero?!?
the documentation says:
@field          mCycleCounter
                       The cycle ordinal number. This number starts at 1 for the first IO cycle and
                        increments for each subsequent IO cycle. The count will recycle back to 1
                        whenever the IO thread resynchronizes with the hardware.
Is it a known issue?

Thanks for your help,

Bertrand
