Hello! I’m having an issue where my Voice Assistant, on the latest 12.1 firmware, is clipping hard on the audio-out. I say clipping, but what I mean is it’s super distorted. I assume it’s from clipping because it sounds like when your mic gain is too high on a crappy mic. I recently bought a bunch …

[image] Sawtaytoes: Then I tried using Google Chromecast Audio (that really old one they don’t sell anymore) to the same speaker from Music Assistant, and it sounded fantastic! Max volume had no clipping. You cannot compare max volume from 2 separate unrelated devices. To amp the voice PE ou…

I understand that “max” means something different on both devices, but the volume level sounded the same other than heavy distortion on the Voice PE. Lowering the Device Volume You’re correct that lowering the Voice PE volume helps, but then I run into a few issues: I can’t hear it as well (overa…

Take a look at the last posts here: [image] Home Assistant Voice - Aux speaker Hardware Yes, this was also my understanding. But the CB speaker that @TheHuntyBadger linked doesn’t have a external power source. So its a passive speaker that would have to be driven by the…

Is it possible to change this line-out issue in firmware or to use the Grove port somehow? Seems like you nailed it. This is what I was thinking too. If there’s that kinda distortion, it’s because it’s amplified (like for headphones) and not line-level. I don’t have a way to turn down the unit and…

I’ve got more data! Took a while to get this set up, but I recorded the 3.5mm output of the Voice PE and the Chromecast Audio for the same song: [image] Top: Voice PE Bottom: Chromecast Audio [image] ["Desk speakers" is the Chromecast Audio.] [Everything is disabled, so it can output as lo…

[image] Sawtaytoes: I read that the RMS is 2V (2.8Vmax peak) for the Chromecast Audio on the AKM 4430 DAC chip. Isnt clipping a setting issue. With distortion being DAC, processor, etc? Outside of direct failure of hardware I cant think of a cause for clipping outside settings (source input…

It’s clipping [image] tmjpugh: Isnt clipping a setting issue. With distortion being DAC, processor, etc? I wrote “distortion” because all I knew is it sounded bad, and I thought it was clipping but didn’t have any measurements. Now that I’ve done some measuring, it’s clearly clipping; you c…

If you want more details on this, you could try to open a discussion on Discord in the hardware section and set the voice pe tag. The devs are more likely chiming in there instead of the forums here.

Thanks for that info! :slight_smile: I went ahead and put up a thread on Discord

Someone showed me a schematic of the Voice PE’s audio interfaces, and showed that the amplifier only goes to the speaker, not the 3.5mm jack meaning it’s coming direct from the DAC with that horrible sound quality :frowning:.

Voice PE DISTORTED audio?

Take a look at the last posts here:

Seems to be somewhere between line-out and pre-amplified.
So you most likely have to test around at which level you get a good gain without distortion, but avoid base noise because of too low levels…
