Hi,
Please try building Buildroot exactly as explained here: https://boundarydevices.com/buildroot-2020-08-for-imx-platforms/
Audio was working with this config. Maybe the kernel was more up to date in our external layer though.
Regards, Gary
Hi Gary,
Same error with this version.
# aplay /ring_sound.wav Playing WAVE '/ring_sound.wav' : Signed 16 bit Little Endian, Rate 44100 Hz, Stereo aplay: pcm_write:2061: write error: Input/output error
Trying to play a video (in the tuto): no sound Trying to play an audio file using: "gst-launch-1.0 -v uridecodebin file:///ring_sound.wav ! audioconvert ! audioresample ! autoaudiosink: no sound and gst-launch never finish (on my PC, this pipeline ends at the end of the audiofile)
Note: I am using an headset + micro (I don't have HP to connect directly to the board).
Thanks
Hi, Please try this branch then: https://github.com/boundarydevices/linux-imx6/tree/boundary-imx_5.4.x_2.2.0 If it doesn't work there must be something wrong with the setup. I usually test with headset as well. Regards
Hi,
Same with this version:
Linux version 5.4.72 (adgra@adgra-XPS-15-9570)
aplay /ring_sound.wav Playing WAVE '/ring_sound.wav' : Signed 16 bit Little Endian, Rate 44100 Hz, Stereo aplay: pcm_write:2061: write error: Input/output error
Hi, I just tried the latest Linux version and it works as expected:
root@nfs:~# uname -r
5.4.72-g3b0d9a0a12eb
root@nfs:~# aplay song.wav
Playing WAVE 'song.wav' : Signed 16 bit Little Endian, Rate 44100 Hz, Stereo
Have you tried the prebuilt Buildroot images from the blog post? IIRC I tried playing BigBuckBunny and checked the audio back then.
Could you please send me the wav file you are using (maybe my file is corrupted / special)?
I will try the prebuilt image.
Thanks,
Same with the jenkins version and your file :(
(Linux version 5.4.60 (jenkins@ae899e375adb))

I have a nitrogen8m_mini board "rev30 06-28-2019"
I have an older version of the board (rev20). Please copy/paste your bootlog into pastebin. Also, please make sure to have latest UBoot (just in case).
Complete dmesg: dmesg.txt
I think I will take some time to investigate this (after mainlining my patches on kernel).
Thanks,
I've seen people havin issues with SDMA with newer kernel and old U-Boot/ATF. Please make sure you have the latest.
Same issue with latest u-boot (U-Boot SPL 2018.07-01626-g338e38fa4e (Nov 25 2020 - 17:17:56 +0100).
Thanks,
Sorry to post to an old issue, but I am seeing the same problem with the Boundary imx8m plus EVK. When I run with a recent "Boundary XWayland 3.2 (gatesgarth)" yocto release the song.wav plays fine over my headphones. But with the recent Boundary 2021.05 release I get no audio and this error:
# aplay /opt/song.wav
Playing WAVE '/opt/song.wav' : Signed 16 bit Little Endian, Rate 44100 Hz, Stereo
aplay: pcm_write:2058: write error: Input/output error
The 5.4.110 kernels between my yocto and buildroot were almost identical. But, just to eliminate the kernel I copied the Image
and imx8mp-a0-nitrogen8mp.dtb
out of yocto and into the buildroot /boot dir (The kernel modules were still from buildroot) But, I still get the same error from aplay. I am guessing there is some important user space difference here between yocto and buildroot. Maybe alsa libraries (I have no idea)?
Here are the versions I am testing with:

Hello,
With BuildRoot mainline (nitrogen8mm_defconfig + alsa + tinyalsa, kernel 5.4 boundary devices, boundary_defconfig), I tried to play audio on my nitrogen8m-mini board with aplay (alsa) and tinyplay (tinyalsa) and I am facing an error.
The audio device seems to be listed by the kernel (ALSA device list: #0: wm8960-audio), but with aplay and tinyplay are exiting on error after about 10s (and no audio played).
# aplay /ring_sound.wav Playing WAVE '/ring_sound.wav' : Signed 16 bit Little Endian, Rate 44100 Hz, Stereo aplay: pcm_write:2058: write error: Input/output error
# tinyplay /ring_sound.wav playing '/ring_sound.wav': 2 ch, 48000 hz, 16 bit error playing sample
With the same board (but different kernel version) I am able to play sound with Android (with UI, not tested with aplay nor tinyplay).
I think I am missing something on BR, Could you please help me? (I need to play audio to verify that my driver integration is OK on mainline)
Thanks,
