Audio codec rt5631 on TX2 Jetpack 4.4

I wanna use I2S0 to connect with ALC5633 too.

Audio codec rt5631 on TX2

Dear all, I wanna use I2S0 to connect with ALC5633 audio codec and I found out that rt5631 codec driver already inside kernel source code. When I tried to config kernel menu it was so hard to see which module should be selected to build as well as how to modify the device tree to load that module. Any help would be appreciated. Thanks and Best Regards, Vu Nguyen

so i followed that threads but a sound is not works. sound’s out pin works but i think that sound data is not coming anything. if playing some sound
device driver works someting

I think that point is different Jetpack version.
for example Jetpack 4.4 is not using tegra_t186ref_mobile_rt565x.c and instead of using tegra_machine_driver_mobile.c

But that be all… am I missing something?

My change point is like this

When playing sound rt5631 device driver looks work well and any other errors.
but sound data is not incoming.

[sharadg]

Hi,

The post https://forums.developer.nvidia.com/t/audio-codec-rt5631-on-tx2/59379 is very old.

Kindly refer to the codec porting guide here and ensure below :

1. Check if codec is registered (cmd: sudo cat /sys/kernel/debug/asoc/codecs | grep 5631 )
2. Ensure pinmux settings are done correctly (cmd: sudo /opt/nvidia/jetson-io/config-by-function.py -o dtb i2s1 aud_mclk; sudo reboot)
3. Check if sound card registration is successful (cmd: cat /proc/asound/cards)
4. Check if DAPM path is setup fine during the usecase
5. If playback is still not working, kindly provide mixer control settings and register dumps as per the information in troubleshooting guide available at here

Thanks,
Sharad

alc5633 and rt5631 is almost similar at least it can hear sound so reason why using rt5631 but default rt5631 is not work. and rt5631 dapm have errors too.

i checked your suggstion

1. codec is registered
2. nothing changed
3. rt5631’s DAPM has a lost of errors
   i checked others but
   i dont know why x OUT. x IN still got error. is those declared in tegra186-quill-common.dtsi?

trouble shooting saying CONFIG_SND_SOC_SDPIF=y … but nothing changed and CONFIGS not using that too

[sharadg]

It seems DAPM routes are not updated : Please try changing DAPM routes as mentioned in the comment Audio codec rt5631 on TX2 - #16 by jonathanh.

[nkw3000]

i already added but still remained

[sharadg]

This is bit confusing. DAPM route error wasn’t observed as per you first comment.

Can you share “hardware/nvidia/platform/t18x/common/kernel-dts/t18x-common-platforms/tegra186-quill-common.dtsi”?

Routing looks ok in the attached file. Could be an issue with Device tree file used on Jetson. Please share more info : On Jetson :
# dtc -I fs -O dts /proc/device-tree >/tmp/dt.log
# cat /proc/device-tree/sound/nvidia-audio-card,routing > /tmp/dapm.log

Attach dt.log and dapm.log.

Audio codec rt5631 on TX2

Dear all, I wanna use I2S0 to connect with ALC5633 audio codec and I found out that rt5631 codec driver already inside kernel source code. When I tried to config kernel menu it was so hard to see which module should be selected to build as well as how to modify the device tree to load that module. Any help would be appreciated. Thanks and Best Regards, Vu Nguyen

but my case i added some msg in “nvidia/sound/soc/tegra-alt/machine_drivers/tegra_machine_driver_mobile.c”

tegra_machine_driver_probe …
printk(“%s :: codec_name"%s" registered\n”, func, card->dai_link->codec_name);

printk(“%s :: codecs->dai_name"%s" registered\n”, func, card->dai_link->codecs->dai_name);

I2s1_sync_clk is not setting and placed wrong

I tried to ALC5633 I2S porting however I2S signal and data is not work so i searched what happen. HW is ok cuz other old TX2 kernel is works well but my Jetpack 4.4 is not work . and i found something wrong. sudo cat /sys/kernel/debug/clk/clk_summary why i2s1_sync_clk is under spdifin_sync_input ? and i2s1_sync_input is setting wrong clk? i using default clock setting and i want to set i2s1_sync_clk but i cant find how to set. thx *[ default_freq …

JETPACK 4.4 need a change to i2s1 pinmux setting
