I haven’t checked my MNT Reform yet, but my pocket is currently soundless via either the headphone jack or the internal speaker. I can get sound to work via bluetooth, but it gets choppy and eventually drops after a few minutes – I am assuming that’s unrelated, but I thought I’d mention it.
Gnome reports only a single output, and in settings it’s called Analog Output - Built-in Audio and there are no other devices.
Previously, I was able to fix things via alsamixer, but that does not appear to be the case with whatever is going on right now – by default, it seems to show a very simple pipewire screen with a single volume slider. Selecting audio cards presents me with options for (default) -, hdmi1, and rk3588-tlv320aic3100, the latter of which has many devices, which seem to have zero impact on sound output. The single output Gnome is displaying seems to correspond to the (default) - output, which alsamixer is labelling PipeWire.
dmesg output has this:
[ 50.273962] asoc-audio-graph-card analog-sound: ASoC: driver name too long 'rk3588-tlv320aic3100' -> 'rk3588-tlv320ai'
This appears to be a red herring (reform-hw-setup uses the name rk3588tlv320aic and changing it to the version without a c and adding a dash generates an error message).

I: Version of keyboard firmware: "20250117"
I: Version of U-Boot: 2024.10-g424c714eb247-dirty
I: Latest version of U-Boot: 2025-11-04
I: probably booting via /boot/boot.scr (/boot/extlinux/extlinux.conf does not exist)
I: Mount source of /: /dev/reformvg/root (LVM vg 'reformvg' on LUKS device 'reform_crypt' on SSD)
I: Mount source of /boot: /dev/mmcblk0p1 (eMMC)
I: Suggests of reform-desktop-minimal is not installed: firmware-iwlwifi
W: you do not seem to boot using tuigreet but you the following file sets your loglevel to 3: /etc/flash-kernel/ubootenv.d/00reform2_tuigreet_loglevel -- you may consider removing it and re-running 'sudo flash-kernel'
I: the following files differ from how they are shipped by reform-tools (ignore /var/lib/alsa/asound.state):
??5?????? /var/lib/alsa/asound.state
I: the reform-qcacld2 package is only required for wifi on the Pocket Reform with i.MX8MP, you can safely remove it unless you plan to go back to the imx8m+
I: kernel boot parameters your system does use but which are not the default:
+ loglevel=3
I: kernel boot parameters which are the default but your system doesn't use them:
- console=ttyS2,1500000
I: eMMC contains the latest u-boot version 2025-11-04
I’ll keep poking at it – let me know if there’s anything specific I can do to help troubleshoot (or if I’ve done or missed something incredibly silly).
