app_avb_lc Channels swapped

[marcohabeck]

The channels are swapped for select channel.

push button one LED 3 & 4 mapped stream channel 7 & 8
push button three LED 7 & 8 mapped stream channel 3 & 4

Cause is an error in the code main.xc 357-367.

map [j] = map [j]% AVB_NUM_MEDIA_OUTPUTS; so can not work.

The rest of 6 and 7 is 0 to 1. which maps the channel on 7 & 8th

This code works.

if (map[j] != -1)
                {
                  map[j] -= 2;

                  if (map[j] < 0)
                  {
                    map[j] = map[j]+AVB_NUM_MEDIA_OUTPUTS;
                  }
                }
              }
              avb.set_sink_map(i, map, len);
            }
