It seems only the right channel works on my Pocket Reform with the built-in speaker. Headphones work fine on both channels. Is that expected or is something wrong? I think the machine does this since I received it.
- Which processor module?
- Does it also happen when booting from a MicroSD card with the default System Image?
RK3588, 32GB
I am on the road so I don’t have a MicroSD handy. Will check at home.
I encountered a similar issue, I’m not sure if the default ucm profile has been changed in the last few months but I updated mine to ensure that it had mono output for the built in speaker, rather than just one channel.
This is the config I’m using:

I booted from a microSD, same effect. Test in GNOME sound settings works for left but not right.
Thanks. I have to admit that I am not sure where I would find the original version of this file on my machine that I would need to patch?
So /usr/share/alsa/ucm2/conf.d/rk3588-tlv320ai/HiFi.conf needs to be edited. This is the diff:
41,43d40
< cset “name=‘DAC Left Input’ Mono”
< cset “name=‘DAC Right Input’ Off”
<
So in line 41 these two lines need to be added.
That would need to be changed here:
https://source.mnt.re/reform/reform-tools/-/blob/main/audio/ucm2.conf.d/rk3588-tlv320ai/HiFi.conf
My registration for the Gitlab is pending, otherwise I would be happy to do a merge request.
Thanks @bpye for pointing out the needed correction!
If you don’t want to wait, send me a name and email with which you want to be mentioned as author in the git metadata and I can create a commit for you. Or send me a git-format-patch.
I’d reference "B. Pye" <hello@bpye.ca> in a Thanks field.

Sorry for not getting back to you on file location, though I would have just been guessing for Debian. Glad it worked out!

I chose to do it differently now.
@bpye I see that you have a few more small changes to the ucm profile. I now put everything you have into this MR:
https://source.mnt.re/reform/reform-tools/-/merge_requests/175
You are the commit author and I reference your nixos repo in the commit message. Please tell me if you’d like me to do this differently.
I’d need a review from @minute for this MR.

Hm it seems like I’m no longer able to access source.mnt.re on my home WiFi, though cellular does work. On my home connection any attempt times out.

@minute is batteling with crawlers DDoS-ing source.mnt.re and had to block literally millions of IP addresess because crawlers use residential IPs to disguise their traffic as legitimate one. You could contact @minute privately with your IP to get this sorted.
