CYW20706:I2S_WS signal level and L/R channels

[towa_2281366]

Hi,

We had encountered the same problem as the  following post:

https://community.cypress.com/t5/WICED-Studio-Bluetooth/CYBT343026-I2S-WS-signal-level-and-L-R-chann... 

But there is no bug-fix-patch attached, can anyone tell me how to fix it ?

(sdk : wiced 6.4)

It's urgent, thanks!!!

Hi,

How are your kit's pin configuration and deployment? How do you test and confirm that you have the flipped results?

Best regards

[towa_2281366]

pin configuration:

I2S_BCLK:I2S_CLK/PCM_CLK/P2/P37/P28(B7)
I2S_WCLK:I2S_WS/PCM_SYNC/P0/P34(C8)
I2S_DOUT:I2S_DO/PCM_OUT/P29/P3/P35(A8)
I2S_DIN:I2S_DI/PCM_IN/P12(C7)

test:

20706: working as a2dp source and i2s master ,start a2dp stramming with api:

wiced_audio_start(TRUE, AUDIO_ROUTE_I2S, media_cid, &sbc_caps_configured )

Capture I2S signal using saleae logic  while 20706 trasmitting music to remote headphone, only feed i2s with left channel data ("0" when WCLK is high), in the meanwhile, headphone's right  channel has sound out (should be left channel)
