Starbeamrainbowlabs Posted August 5, 2019 Share Posted August 5, 2019 Armbianmonitor: http://ix.io/1QFr I'm testing out the Orange Pi 3 Ubuntu 18.04 image (Link: https://www.armbian.com/orange-pi-3/), and I'm trying to play some sound using a USB adapter (Link: https://www.amazon.co.uk/gp/product/B000R5NJD8/). I originally posted this as a question on Ask Ubuntu (link: https://askubuntu.com/questions/1163369/sound-only-1-speaker-is-working), but I was advised to file a bug report about the issue. I'm acutely aware that this post belongs in the Allwinner H6 forum (Link: https://forum.armbian.com/forum/18-allwinner-h6/), but it would appear that there are restrictions in place to prevent me from posting there. It works...... but only through the left speaker. If I do this: speaker-test --test wav --channels 2 ...I hear "front right" out of the front-left speaker, and I do not hear "front left" at all. If I instead test just 1 channel: speaker-test --test wav --channels 1 ...then I hear "front left" out of the front-left speaker. The same goes for if I play some music with `aplay`: aplay test.wav I ran the `alsa-info` program, and got this link, which contains a bunch of useful information: https://alsa-project.org/db/?f=39d0b2d680cd04a510e0bc0615d7ba771f4b29d2 I've checked the levels in `alsamixer` already: https://i.stack.imgur.com/N7U0f.png (Link to screenshot of the terminal) alsamixer -c1 Additionally, I checked the USB adapter in question on another (also Ubuntu) machine (that has a GUI) (`alsa-info` link: https://alsa-project.org/db/?f=2f7f9550539333685966e7fd35ace8524281ba40). Both channels worked flawlessly as intended. I do have PulseAudio installed, but playing through that yields the exact same problem. Does anyone know what's gone wrong? I'd very much like to listen to things through both speakers. Link to comment Share on other sites More sharing options...

Armbian is small amateur based project focused to onboard hw, which is hard enough, with virtually no budget for R&D. 1 hour ago, Starbeamrainbowlabs said: I'm acutely aware that this post belongs Not anymore. But that does not change anything for you - it was only to lower our costs. 1 hour ago, Starbeamrainbowlabs said: I'd very much like to listen to things through both speakers. This issue is more or less generic (moving to peer to peer section) and tied to this particular (5.1.y) kernel I would guess. Most simple thing which you can do is to compare kernel configurations between working and non-working one, especially in sound section. Then check LKML for alsa related bugs ... and if/when you find a problem, submit a patch. Link to comment Share on other sites More sharing options...
Starbeamrainbowlabs Posted August 5, 2019 Author Share Posted August 5, 2019 Hey! Many thanks for the reply, @Igor. I tried my best to find the most appropriate place, but I must have gotten confused 5 hours ago, Igor said: compare kernel configurations between working and non-working one, especially in sound section I see. How would I go about doing that? Where can I find the appropriate kernel configurations to compare please? 5 hours ago, Igor said: Then check LKML for alsa related bugs Not sure I know what "LKML" refers to, sorry. 5 hours ago, Igor said: and if/when you find a problem, submit a patch I assume that would be against a git repository somewhere? I'm certainly open to doing so, but it sounds rather intimidated at the moment Link to comment Share on other sites More sharing options...
Igor Posted August 5, 2019 Share Posted August 5, 2019 Solution is not simple.
