Hi, hongwan,
Joan's answer is correct, you only need to remove "codec-master" from "sound" node:
mux-int-port = <2>;
mux-ext-port = <3>;
- codec-master;
hp-det-gpios = <&gpio7 8 1>;
mic-det-gpios = <&gpio1 9 1>;
BUT I don't know if you have configured dai format and cpu clock in "machine driver" like code below:
static int imx_hifi_hw_params(struct snd_pcm_substream *substream, struct snd_pcm_hw_params *params)
{
struct snd_soc_pcm_runtime *rtd = substream->private_data;
struct snd_soc_dai *cpu_dai = rtd->cpu_dai;
u32 channels = params_channels(params);
u32 rate = params_rate(params);
snd_pcm_format_t sample_format = params_format(params);
int ret = 0;
ret = snd_soc_dai_set_fmt(cpu_dai, SND_SOC_DAIFMT_I2S
| SND_SOC_DAIFMT_NB_NF | SND_SOC_DAIFMT_CBS_CFS);
if (sample_format == SNDRV_PCM_FORMAT_S24_LE || sample_format == SNDRV_PCM_FORMAT_S20_3LE)
bclk = rate * 384;
else
bclk = rate * 256;
ret = snd_soc_dai_set_sysclk(cpu_dai, 0, bclk, SND_SOC_CLOCK_OUT);
.... ...
}
Probably above code should be modified according to your codec datasheet, BUT you can try .
Have a nice day!
