Hello, I'm new to ALSA and linux in general, I need help from who knows well ALSA due to the tight schedule of the project. I'm working on a Yocto project on NXP i.MX6Quad. The hardware architetture is this: the i.MAX6Quad has 6 output connected to 3 ST FDA2100 and 2 input from ADC. In the first step what I need is simply to enable 6 output and send I2S audio to FDAs. In the second step is required a clock for ADC and enable input ports. I spent days/weeks reading docs, examples etc without success. I understood that working on device tree file and setting a simple audio card with generic codec properly is the answer, but my knowledge is almost nothing. I followed these docs/thread https://elixir.bootlin.com/linux/latest/source/Documentation/devicetree/bindings/sound/simple-card.txt https://community.nxp.com/thread/475428 but compiling I have syntax errors on device tree file. There is someone who can help me step by step? Thanks in advance Riccardo _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx http://mailman.alsa-project.org/mailman/listinfo/alsa-devel
