Hi, everyone:
I have added the rt5651 codec’s driver, we used the driver in linux kernel, and we have modified the device-tree and tegra_t186ref_mobile_rt565x.c, we could see that t5651’s codec driver worked well, but when I used the command: aplay -D hw:1,0 Noise.wav, to play wav, I could not hear the sound. follow is trace message:

and when I make the follow change in dts:

sound {
         nvidia,audio-routing = "x Headphone", "x LOUTL", "x Headphone","x LOUTR";
}

then I used the command " aplay -D hw:1,0 Noise.wav" to play, there is no sound can hear, and the trace message is:

Hello!

Looking at the rt5651, I see it has both line-out and headphone outputs. From the above it appears that you are trying to use the line-out outputs, is this correct?

So for using the line-out the following route looks fine …

sound {
         nvidia,audio-routing = "x Headphone", "x LOUTL", "x Headphone","x LOUTR";
}

However, from the trace you can see that the I2S interface is not being enabled and so what this typically means is that the route within codec is not configured completely. The ALSA lib contains some UCM (use-case manager) examples for the rt5651 [0] and so maybe something like the following could work …

amixer cset -c tegrasndt186ref name="x LOUT R Playback Switch" on
amixer cset -c tegrasndt186ref name="x LOUT L Playback Switch" on
amixer cset -c tegrasndt186ref name="x LOUT MIX DAC L1 Switch" on
amixer cset -c tegrasndt186ref name="x LOUT MIX DAC R1 Switch" on
amixer cset -c tegrasndt186ref name="x Stereo DAC MIXL DAC L1 Switch" on
amixer cset -c tegrasndt186ref name="x Stereo DAC MIXR DAC R1 Switch" on
amixer cset -c tegrasndt186ref name="x OUT Playback Volume" 31
amixer cset -c tegrasndt186ref name="x DAC1 Playback Volume" 175
amixer cset -c tegrasndt186ref name="x Headphone Jack Switch" on

Jon

Hi, jonathanh:

  Thanks for your answer. I checked the rt5651's chip manual, I found that the  route was set wrong. after I change the route in amixer_settings according the manual, I can hear the sound from HeadPhone() and SPK(LOUTL/LOUTR).

Regards,
Michale
