Hello everyone, I am using an X310 with a UBX-160 daughter card to playback many hours of recorded samples.
After a few hours, even when using a very powerful server, some underflows accumulate. This impacts the timing of data being played back. In some cases a 24 hour playback will accumulate 100 ms of error. I can obviously solve the problem by periodically stopping the flow of data, and realigning the sample stream and the radio clock, but this isn't desirable. It would be unfortunate to drop seconds of data to handle a few underflows. Is there a standard way to handle this with the UHD API? I'm calling send() on the tx stream with 10 ms of data at a time. If I use a time spec for every 10 ms buffer, and an underflow causes a late packet, will the X310 just drop the late 10 ms of data, and realign itself on the next buffer? Or will every subsequent buffer be late? All of the UHD examples only ever set a time spec on the first buffer of samples, which suggests this will not work. Thanks, Armon
