Support For DRM+

[vestel5g]

Dear,
In our lab we are trying to execute DRM+ (apps/grc_flowgraph) in Gnu Radio 3.7 on Ubuntu 14 and USRP B210.
GitHub repository "kit-cel / gr-drm Public"

git checkout -b cea51e7

As per your advice we changed the parameter
Audi Source
[Sample Rate =24KHz ]

When we trying to execute the GRC file following comments appears on the terminal.

INFO: Audio source arch: alsa

sched: <block cell_mapping_cc (35)> is requesting more input data
than we can provide.
ninput_items_required = 29840
max_possible_items_available = 22527
If this is a filter, consider reducing the number of taps.
cell interleaver init: filling buffer
cell interleaver init: filling buffer
cell interleaver init: filling buffer
cell interleaver init: filling buffer
cell interleaver init: filling buffer

what is the issue how to fix the issue and execute sucessfully.

We are looking forward for your advice and support.

Thanks
