Hello,
I using the Samsung Galaxy Buds2 Pro headphones to connect to the latest v2.4.0 nRF SDK. I am using the LE Audio demo code as gateway. The demo connects successfully out of the box to the headphones, with some modifications to the prj.conf file, using the nRF5340 Audio DK. For my project needs, I have both source and sink enabled via CONFIG_STREAM_BIDIRECTIONAL.
CONFIG_AUDIO_DEV=2 CONFIG_BT_DEVICE_NAME="Galaxy Buds2 Pro" #QOS will fail without this CONFIG_BT_AUDIO_PRESENTATION_DELAY_US=40000 #Seem to get failed to discover without this CONFIG_BLE_ACL_CONN_INTERVAL=72 CONFIG_BT_AUDIO_MAX_TRANSPORT_LATENCY_MS=100 CONFIG_LOG_BUFFER_SIZE=8192 CONFIG_BT_AUDIO_RETRANSMITS=2 CONFIG_BT_BAP_UNICAST_CLIENT_ASE_SRC_COUNT=2 CONFIG_STREAM_BIDIRECTIONAL=y CONFIG_WALKIE_TALKIE_DEMO=y CONFIG_AUDIO_SOURCE_I2S=y CONFIG_BT_BONDABLE=n CONFIG_BT_VCP_VOL_CTLR=n
Problem #1 - Controller Crashes
If you connect to the right headset first, then connect to the left headset, the"ble5-ctr-rpmsg_3349" controller crashes. I believe this also happened on the 3330 controller as well.
The crash happens after calling bt_bap_stream_start on the Left SINK. This only happens if you connect to the right headset first, followed by the left.
Once the controller crashes, the next call to bt_hci_cmd_send_sync will fail on semaphore take "timeout with err -11". This usually happens either on the next le_audio_send stream send OR on the ble_core.c watchdog call to net_core_ctrl_version_get.

Problem #2 - Connection constantly disconnects
There seems to be a possible timing issue when connecting a headset stream, then starting the scan / connection to the other headset.
After starting the left headset stream, when you start scanning / connecting to the right headset, the left headset drops connection. It happens as soon as the right headset starts scan / connection. I have noticed that if you start searching for the right headset later in time / further in the code connection sequence, this happens much less frequently. The ACL scan is originally in unicast_client_location_cb. If I move the ACL scan to discover_source_cb or stream_enabled_cb, the issue happens much less frequently. If this is time dependent, then this is also likely a problem because as we add code to the rest of the system, time could change again and cause the issue to come back.

The next issue that I have seen is if you connect to the headset successfully, the first time the connection is made, the source (headset microphone) audio will play on the headphone jack every time. The issue comes when you put the headset back in the case and close the lid, then re-open and take the headset out. The next successful connection will have a 50% chance of the microphone audio playing on the headphone jack. This 50% chance of source audio working happens every time you put the headphones back in the case and take them out again.
One note: I have also tested this on a non-audio DK, with the source audio being fed back into the headset sink. For this reason, I don't think the issue has to do with the I2S or HW codec etc.
Lastly, it looks like the audio in data is still being received since the callback for Rx data is still being called.
I have attached an example project. It is the LE audio demo code with minor modifications. Search for <Modified> in the code to see what I modified. The modifications were only made in prj.conf and le_audio_cis_gateway.c
