I am trying to use the Jetson Nano’s audio through HDMI. I tried this with aplay and gstreamer, but the first part of the wav file is soft and it kinda stumbles into playing the wav file. I’ve attached the wav file I don’t believe the issue is the wav file because it works fine on VLC Media Player …

Hello! Thanks for the update/feedback. It seems to be related to device connected and so it is difficult to determine where the problem lies. I have checked more on our side but we have not observed this and are unable to reproduce. If there is any other information that comes to light please let u…

Hello! I have tried this with the latest L4T/Jetpack release and I was able to play the file fine from the command line using aplay. I did not observe any softness or volume differences between the start and end of the clip. Please can you try the latest release and see if the problem persists. If…

So the second setup I tested is using a different monitor with a different HDMI cable. The problem also occurs in the Sound settings menu with the Test Sound option. The monitor I have with me right now has an AUX output, so I tested it with two headphones which also show me the problem. Both of th…

Hi @jonathanh I I upgraded the Jetpack version to R32.5.0-20210115145440 and I still see the issue.

Hello! I have tried to reproduce this, but so far I have not seen any issues. I have used two different Nano and two different displays (one AOC monitor with built-in speakers and an LG TV). Are your monitors the same brand/model? Here are some videos of what I observe on my Nano … …

The monitors are different. This link to google photos has 6 videos to show it. The first few videos are of a cheap portable monitor (no brand) we got that has a built in speaker. (The portable monitor was not able to use “Front Left”.) The other videos are on a completely different setup (different…

I actually forgot to mention too that the videos on the portable monitor are still on R32.4. The ones on the BenQ monitor are R32.5.

Hi @jonathanh , Anything else I can add to pinpoint where this problem is? No worries, if we can’t find a solution. It’s not extremely important to us.

Hello! Apologies for the delay, I have been checking with the audio team to see what else we can try. Could you try … Adjusting period size and period count with --period_size=1024 --buffer-size=4096 option for aplay. By default it takes huge buffer size(~24k frame size) Adjusting start-delay of …

Thanks for getting back to me. Unfortunately, it doesn’t seem that those options are improving it. I also tried a mixture of them, but I observed no difference.

Hello!

Thanks for testing. Any chance you have a normal TV with built-in speakers that you can try with?
