tlv320aic23b not working on imx6q based board

regangovender · ‎04-18-2016

Hi dear Freescale community,

I need help getting the above mentioned codec working on my board. I'm running debian linux, kernel version 3.10.94. This kernel was given to me by the board manufacturer.

my set up/Configuration:

imx6 <====>tlv320aic23b

i2c sda <====> i2c sda

i2c clk <====> i2c clk

I2S tx<====>i2s din

I2S rx<====>i2s dout

I2S fsx<====>i2s lrcout

||

===>i2s lrc in

I2S blck<====>i2s bclk

The codec uses a 12Mhz crystal to generate its own master clock.

I've started testing using aplay:

when i list devices it gives me :

aplay -l

**** List of PLAYBACK Hardware Devices ****

card 0: imxspdif [imx-spdif], device 0: S/PDIF PCM Playback dit-hifi-0 []

Subdevices: 1/1

Subdevice #0: subdevice #0

When i try to play a file:

aplay -v -D hw:1,0 crash.wav

I've enabled some debug in the codec file. While i exe the aplay command above i get the following debug:

I'm still checking whether i2c reads/writes to the codc are actually working because if i change the i2c address in the codec node part in dtsi file:

codec: tlv320aic23@1a {

to

codec: tlv320aic23@2a {

for example, the kernel does not complain. It still enumerates the device somehow. Also note that i have already checked out this post which relates to my issue:

How to enable TLV320 on IMX6Q?

Well there you have it. If anyones got time to check this out and give me some pointers , it'll be great.

Thanks for your time.

This time the issue was that i wasn't enabling capture on the line in using alsamixer. So you need to go on line in and hit spacebar then you see the L/R capture text in red.

The issue was that the i2c writes to the codec were failing. I moved the codec node into the correct i2c bus node in my board .dtsi file. Now i am able to play audio successfully.

My issue now is that i'm recording stereo audio but when i play it back its playing as mono.

To play i'm using mplayer:

mplayer -ao alsa:device=hw=1.0 -srate 48000 Stereo-Audio-Test-Left-Right--4bJ0dvAl98k-www.mp3tunes.tk.m4a

and at the same time i run arecord(line out connected to line in on my board):

arecord -f S16_LE -c2 -r48000 --max-file-time 100 -D hw:1,0 -V stereo test.wav.

Now when i play back test.wav left and right channels are combined and i get mono. I dont know whether the codec or whether alsa/linux audio driver is combining it.

Am i missing something? Does anyone have any ideas?
