I recently purchased a Jetson TK1, and after a week of using it without problems, I am now beginning to experience issues with sound output.
I have two separate issues: HDMI sound out no longer works, and the system does not detect headphones when plugged in.
For the first issue: I have been using the TK1 with HDMI sound output to my monitor without issues, but this morning, I was forced to switch to my TV, and I no longer have access to the monitor I was using. With my TV, the system won’t make any sounds. I have gone to sound settings and ensured that HDMI is selected as the sound output device, I have checked that the TV has the volume up and not muted, I have checked that Ubuntu’s sound is up and not muted, and I have checked that the TV sound works with other devices that connect with HDMI. I have also made sure that the connections are solid and I have tried multiple HDMI cables. I checked around for similar issues but I couldn’t find anything :(
For the second issue: I have not tried connecting the headphones before, so it’s not like the first problem where it worked before and now it doesn’t. To see if the first problem was with Ubuntu or with the board itself, I tried connecting my headphones to the board, but for some reason, Ubuntu does not even detect my headphones as an output device. I’m sure it’s just an issue of drivers or something like that, but I couldn’t figure it out on my own.
Thanks in advance
