DUDUOS 3.7: Experience the Evolution - Official Release Now Rolling Out 260131

MariusXL

Hi. After the latest update i have horrible distortion over coaxial when the volume is at maximum, i have to reduce the volume level to 28 for the coaxial to not distort. Previously, didn't had any distortion at maximum, especially over coaxial. All the audio enhancements are turned off, sample rate is set at 48khz and usb audio is off. Forgot to mention this dudu unit is the 9.5 inch version with 12gb ram and 512gb rom, canbus is the hiworld for the audi a3.

MariusXL what source / player are you using? I've tested and with 1khz 0dbfs signal dudu 3.7 clips at 34 level in spdif passthrough. Acceptable. However, with USB audio player, clips at 25 which is not Dudu issue but UAPP, somehow it bumps the volume up internally.

edd_stark08 no it doesn't.

@DUDU-Meng can you tell me which PIP controls which one? This is too generic and I have no idea which Picture in Picture I am changing. There's no instructions and there is no definitions to point us to what is being fixed. I'd like to adjust the main PIP where I use map and the widgets texts at the bottom of the screen. Thanks.

using UAPP.
might be some UAPP issue, but it worked fine before the update.
so, level 34 is clipping no matter what player is used? why would it clip at all???

from listening, i went down to level 24 to get clean output from UAPP.

thats all weird, i wish i just could use an USB audio card, but that would kill the bluetooth handsfree phone functionality, sadly.

Mikescotland I'm using Spotify, lossless downloads at 48khz passthrough. Didn't had this problem before update and it's weird to clip over coaxial since no other gain or audio enhancements are on. It shouldn't be clipping at max volume over coaxial, if i would have used rca's i could understand but, over coaxial and toslink you need to have max volume on head unit if you don't want to chop the bit rate/depth.

Mikescotland

Eule it clips with 0dbfs with audiotools.
So far I can see that only UAPP is doing something strange, so I believe this isn't related to duduOS (tidal, poweramp, etc, all good). Getting down by -6.4dB volume in uapp sorts it out.
Normally all audio devices I've tested clip at the max volume, so it would be 36 in Dudu. It does clip at 34 though, which isn't ideal.

Tomasz898989 In my case exactly the same. Update reset waze to default setting. Additionally I have voice issue. When I receive warning form users and I touch screen for confirmation or cancellation the application loses voice instruction and I must restart unity to regain voice instruction in Waze.

On my mind final version works better than few previous beta - much stable, fluent, i think radio works better - stable signal (undgerground garrage still works where few weeks ago not for some stations).
I'll still test it but want say - very good job.

Would it be possible to implement a toggle in the settings to manage wireless Android Auto functionality? Given the current stability concerns with wireless Android Auto, we could disable this feature and exclusively utilize wired Android Auto connections. Should wireless Android Auto be required, we could then employ a third-party dongle.

anpandiyaraj

Would it be feasible to implement a mechanism that resets Bluetooth and clears the Carlink app cache upon system shutdown or entry into sleep mode? This would aim to ensure a stable initial connection for Android Auto each time the head unit is started or reactivated.
