Arecord fails with pcm_read error

vijayaca · December 13, 2022, 8:07pm

Hi,

I am trying to integrate tlv320aic32x6 with xavier agx dev kit followed instructions as detailed here
asoc-driver-for-jetson-products

codec is connected via i2c1 and i2s2 on 40-pin header.

Speakers works fine, but when I try to record using arecord, getting pcm_read error

nvidia@nvidia-desktop:/mnt/ssd/Jetson-L4T/hardware$ arecord  -D plughw:APE,0 -c 2 -d 2 -t wav -f dat  /tmp/tmp_file2.wav

Looks like DAPM routes are missing, could you please help us setting the missing routes? Attached device-tree, dmesg, amixer controls, registers

tried below, still getting error.
amixer -c APE sset 'I2S2 Mux' 'ADMAIF1'

below are the routes

Hi Vijayaca,
AGX has onboard codec which is connected to ADMAIF1 for playback and capture with alsa configuration in userspace. When you try to use same ADMAIF1 instance it might not work. Please try the below command which uses different ADMAIF instance after reboot of target

amixer -c APE sset ‘I2S2 Mux’ ‘ADMAIF4’
arecord -D plughw:APE,3 -c 2 -d 2 -t wav -f dat /tmp/tmp_file2.wav

Hi vijayaca,
I can see aplay DAPM path was completed.

For arecord, you need below mixer control setting
amixer -c APE sset ‘ADMAIF4 Mux’ ‘I2S2’

vijayaca · December 14, 2022, 10:52am

Hi Kumar,

I did try this same result. Do we have to enable any widgets to enable capture DAPM path to complete?

mkumard · December 14, 2022, 11:42am

Hi Vijayaca,
Can you try the below change in the codec driver

/sound/soc/codecs/tlv320aic32x4.c
– SND_SOC_DAPM_ADC(“Right ADC”, “Right Capture”, AIC32X4_ADCSETUP, 6, 0),
++ SND_SOC_DAPM_ADC(“Right ADC”, “Capture”, AIC32X4_ADCSETUP, 6, 0),

– SND_SOC_DAPM_ADC(“Left ADC”, “Left Capture”, AIC32X4_ADCSETUP, 7, 0),
++ SND_SOC_DAPM_ADC(“Left ADC”, “Capture”, AIC32X4_ADCSETUP, 7, 0),

The routing entries looks fine on the DTS file.

vijayaca · December 14, 2022, 11:45am

Hi Kumar,

Yes, I did these changes already. I am testing with these changes which is failing.

mkumard · December 14, 2022, 12:00pm

Hi vijayaca,
Can you attach the modified version of codec driver at your end. Let me cross check and revert back on any change required.

Also can you confirm whether Audio Playback was working fine?

vijayaca · December 14, 2022, 2:00pm

Hi Kumar,

I confirm playback is working fine, I am able to play audio files using aplay.
This is the only change done on codec

mkumard · December 14, 2022, 5:45pm

Hi vijayaca,
Did some analyze on the codec widgets, routes and your mixer controls settings dump. Can you try to set the value ‘on’ for below mixer control which can help capture path as this is the control variable for the DAPM path for capture. Can you set similar mixer control for all INx switch to “on”

numid=1663,iface=MIXER,name=‘TLV HPL Output Mixer IN1_L Switch’
; type=BOOLEAN,access=rw------,values=1
: values=off

vijayaca · December 15, 2022, 7:40am

Hi Kumar,
I did play with various mixer controls, finally found that setting below make the DAPM path complete for record/capture
amixer -c APE cset name=‘TLV IN1_L to Left Mixer Positive Resistor’ 1
amixer -c APE cset name=‘TLV IN1_L to Right Mixer Negative Resistor’ 1

I am testing the MIC functionality, looks like captured audio volume is very low, any suggestions?

mkumard · December 15, 2022, 7:51am

Hi Vijayaca,
That’s good news. On capture audio low volume, Can you check on the volume control on Codec front. I2S doesn’t have gain control. If codec controls not providing enough gain try using MVC module in the capture path.

Refer Audio Setup and Development — Jetson Linux<br/>Developer Guide 34.1 documentation for more details

vijayaca · December 16, 2022, 12:08pm

Hi Kumar,

Any suggestions on how to set MVC for capture?

mkumard · December 16, 2022, 12:21pm

Hi Vijayaca,
Refer to Audio Setup and Development — Jetson Linux<br/>Developer Guide 34.1 documentation for examples on how to use MVC in the path.
