Hello All,

In my BBB, I have connected a custom Audio-cape(based on BBB Audio cape), and is working fine.I used BB-BONE-AUDI-01-00A0.dts to get my sound card added.

But what ever changes I am making in the BB-BONE-AUDI-01-00A0.dts is not affecting at all.

For eg :- the serial-dir fragment under fragment4 of BB-BONE-AUDI-01-00A0.dts , I made all entries as 0 as given below, and I recompiled and loaded.

serial-dir = < /* 0: INACTIVE, 1: TX, 2: RX */
0 0 0 0
0 0 0 0
0 0 0 0
0 0 0 0
>;

But still the cape is working fine.Why it is not affecting at all ?

Any helps appreciated …

Hi Nizar,

Did you ever resolve this problem? I’m facing a similar problem in that I can capture audio, but my playback does not work. I’m using axr2 for capture and axr0 for playback.
