+Bluetooth nRF_Auraconfig sample
+-------------------------------
+
+ * Buffer count (CONFIG_BT_ISO_TX_BUF_COUNT) to be in-line with SoftDevice Controller (SDC) defaults. This can be changed and optimized for specific use-cases.


Move under Bluetooth samples, as this sample does not have its own section under Samples.
After moving, change entry to following:
