Hi, i'm not sure that's the right place to post the issue. (sorry in advance)

I have a Tascam US-428 Hardware and tried to make it works on Ubuntu 22.04. I followed setup instruction for US-224 and adapted it for the US 428 : https://alsa.opensrc.org/Tascam_US-224

First i had to install firmware manually since hotplug package seems to be no longer available : * `lsusb` shows my hardware correctly : `Bus 001 Device 004: ID 1604:8000 Tascam US-428 Audio/Midi Controller (without fw)` * I downloaded firmwares from https://github.com/alsa-project/alsa-firmware * Loaded it to the Tascam : `sudo fxload -s alsa-firmware/usx2yloader/tascam_loader.ihx -I alsa-firmware/usx2yloader/us428fw.ihx -D /dev/bus/usb/001/004` * I manually copied `alsa-firmware/usx2yloader/` files (us428.conf, us428.prepad, and us428.rbt) to `/usr/lib/firmware/usx2yloader/` folder to make `usx2yloader` working. * Running `lsusb` confirmed it works. It shows now : `Bus 001 Device 005: ID 1604:8001 Tascam US-428 Audio/Midi Controller` * Also, the USB led on my Tascam turned up green.

Then I tried to launch us428control to test midi : * `us428control -v 2` properly logs midi event when i move some controls on the Tascam.

So far so good.

Then i tried to test audio playback. ALSA properly list my device : ``` aplay -l ... card 1: USX2Y [TASCAM US-X2Y], device 0: US-X2Y Audio [US-X2Y Audio #0] Subdevices: 1/1 Subdevice #0: subdevice #0

aplay -L ... hw:CARD=USX2Y,DEV=0 TASCAM US-X2Y, US-X2Y Audio #0 Direct hardware device without any conversions plughw:CARD=USX2Y,DEV=0 TASCAM US-X2Y, US-X2Y Audio #0 Hardware device with all software conversions sysdefault:CARD=USX2Y TASCAM US-X2Y, US-X2Y Audio #0 Default Audio Device dmix:CARD=USX2Y,DEV=0 TASCAM US-X2Y, US-X2Y Audio #0 Direct sample mixing device usbstream:CARD=USX2Y TASCAM US-X2Y USB Stream Output ```

Then i tried to playback a wav file : `aplay -D dmix:CARD=USX2Y,DEV=0 test.wav` but when the song finish, or when i interrupt it, my whole system freeze (desktop GUI and mouse) and i had to shutdown my laptop manually.

Note that i tried with other device name but it freeze as well, i also launched Audacity which freeze at startup as well.

I'm a bit lost and i can't find useful information on the internet about it. Any help appreciated. Thanks for reading.
