Has Dynamic Power Management changed?

Audio Gear Talk Verox [formerly RoPieee]

I have Verox 2026.09.1 (4121) [STABLE] on a Raspberry Pi 4 Model B Rev 1.5 with a Justboom AMP/DAC hat.
This setup has run under Ropieee for several years and the Dynamic Power Management would shut off the HAT after Roon stopped playing.
After the upgrade to Verox this no longer works and the connected powered speakers stay powered on.

I am running the latest Verox beta on my Raspberry Pi 5 with Hifi Berry Digi2 HAT and dynamic power management set to 10 minutes. No problem on my end, working as expected.

Maybe worth testing the beta? You can always switch back to the stable channel any time.

I have switched to the BETA channel, when it has updated I will try again.

I am on the Beta channel now but I get the same behaviour, the Justboom AMP/DAC never switches off and the powered speakers stay connected and active.

Thanks Bart. On the JustBoom, the amplifier is switched off when the last service closes the audio device; DAPM then powers down the DAC after the time you set. So my first suspect is that something keeps the device open. Could you tell me which services you have enabled besides Roon, and send a feedback (Advanced → Send Feedback) a few minutes after Roon has stopped playing, while the speakers are still on? Please post the ID here.

As far as I know I do not have any services except Roon running on this hardware. I have used it for several years with Ropieee and it has always shut down a few minutes after the track finishes.

Thanks Bart, that helps. Roon closes the audio device properly when playback stops, and nothing else is using it, so that part is fine.

One thing stands out: under RoPieee your Dynamic Power Management was set to Off, on every build in your logs. Since the move to Verox it’s set to 30 seconds. On the JustBoom the amplifier is switched off by the DAC chip itself when Roon stops, and I suspect that powering the chip down afterwards undoes that. Could you set it back to Off (Audio → Dynamic Power Management), reboot, and let me know whether the speakers switch off again after playback?

Thanks Harry,

that has fixed it, it turns off now. I have sent feedback, 1849c94e61598590, in case you want to look at the logs again.

Great, thanks for letting me know, Bart! Glad the speakers switch off again.
