@IVX I recently updated from my trusty Samsung S10+ to a S24 Ultra. When plugging in the 9038D, the light comes on steady and eventually it will output random passages of the music that is playing at full volume...ear-bleedingly loud, then a bit of full volume static, then nothing, repeat. If I quickly turn off the music app and wait a bit, then turn on the music after the 9038D light has gone off, it seems to work OK. Sometimes I have to do this several times before it settles down and plays music.
I'm not sure who to ask for a fix to this as I don't know if this is a Samsung USB-C audio issue or something with the 9038D. It has not happened with other devices, so I'm leaning towards this being a Samsung bug.
I use Poweramp as my music player app and there was one other strange behavior. When I plug in the DAC, I get a small floating notification (not a proper Android notification) with a Solid Explorer notification that says "Preparing USB Device...". I do use Solid Explorer and have never seen it do this before, but I feel quite certain that the DAC should not trick it into thinking that it is a USB storage device. This happens at the same time as the Tweak9038 app takes charge of the screen.
PS: I uninstalled the Solid Explorer app, and while the notification stopped showing up, the audio issue remained. So, I put it back on.
PPS: I changed the Poweramp setting to Resume Music On Wired Headset Connection, and this does seem to make things better. It allows the Tweak9038 app to wake up and the DAC itself to power on and then settle down. Once I begin the music, no excessive loudness.
Hope this helps any of you out there that are trying this combination of devices yourselves. Damn you, Samsung. Why did you have to go and imitate Apple? If you'd have just stuck with the 3.5mm jack, this would not be an issue.
