Failed to reset CS47L63

Question

Hi,

Failed to reset CS47L63 when swapping the role,

if use the configuration like this:

[
{
"nrf5340_audio_dk_snr": 1050140236,
"nrf5340_audio_dk_dev": "headset",
"channel": "left"
},
{
"nrf5340_audio_dk_snr": 1050167579,
"nrf5340_audio_dk_dev": "gateway",
"channel": "NA"
},
{
"nrf5340_audio_dk_snr": 1000,
"nrf5340_audio_dk_dev": "headset",
"channel": "right"
}
]

everything is fine

if swapping the role like this:

[
{
"nrf5340_audio_dk_snr": 1050167579,
"nrf5340_audio_dk_dev": "headset",
"channel": "left"
},
{
"nrf5340_audio_dk_snr": 1050140236,
"nrf5340_audio_dk_dev": "gateway",
"channel": "NA"
},
{
"nrf5340_audio_dk_snr": 1000,
"nrf5340_audio_dk_dev": "headset",
"channel": "right"
}
]

will be failed:

why? Is the DK broken?
