Thanks for the update btw.

Hi-Res for Kirin 960 stopped working again after update. No Audio but the option is enabled.

Here's the logs:

Hi,

I have a Huawei MediaPad M5 10.8inch with the following specs :-

 

CPU: HiSilicon Kirin 960s, Octa-core; 4×A73 (2.1 GHz) + 4×A53 (1.8 GHz)

Audio : 4 Speakers + 4 SmartPA:

Smart channel switch

Patent Histen sound effects

Harman Kardon tuning and certification

Hi-Res Certificated, Hi-Fi DAC AK4376 and noise cancelling

 

 

The DAC on the tablet has the AK4376 which has the following specs:-

 

AK4376
32-bit Advanced Stereo D/A Converter with Headphone Amplifier
DR,S/N: 125dB THD+N: -107dB Support up to 384kHz Sampling Rate

 

 

Now before the Oreo update the software was working fine and using the DAC correctly 32bit and 384kHz on the wired hires output. After the Oreo update the Hi-Res showed no Wired output so no headphones but your recent update Build 839 fixed the issue and shows Hi-Res wired and working now, BUT only at 192Khz and 16bit or 24bit which is not correct and same issue on build-840, so I'm guessing the DAC is not being used correctly or at all and only the Kirin 960s DAC is being used. I purchased the device and your software because it did work correctly before and for long periods of time it didn't work at all due to Oreo update and no working solution with Poweramp until recent Build 839 and build-840 has same issues too, but still no 32bit and 384Khz as was before the Oreo update.

 

These are the only logs available on the device for Poweramp and as can be seen it only shows 192Khz and no mention of the DAC and also there is none of these files on the device :-

audio_io_policy.conf

Tablet details here :- https://consumer.huawei.com/uk/tablets/mediapad-m5/tech-specs/

 

The device is also Hi-Res Certified .

 

Any help to make this device work correctly would be great, as I only purchased it for this reason as it had a great DAC and your software made it shine and work great before the Oreo headache update that broke Hi-Res support for wired and I don't want to use external DACs and that was the reason for this device as it had a Great DAC built in.

 

Thanks and hope to hear from you with a fix and also some reasons why the missing files on this device on Oreo (not sure if they were there before as all worked 100% before this update) :-

Missing files.

audio_io_policy.conf

Is it possible to add option to have blurred album art library background in addition to the new visualisation library background which does look fantastic!!

@Purgatory thanks for the detailed report. Many Huaweis do declare 384kHz but all device I have on hands fail to play anything with this sample rate, so it’s disabled. I’ll try to get MediaPad for tests and if it supports 384kHz for current ROM, 384kHz will be reenabled. (Please note that OEMs may modify audio features in ROM updates, for example Samsung “nerfed” their Hi-Res support for all major Android versions 7-8-9 and Qualcomm based ROMs downgraded it for 8-9). As for bits, Poweramp always tries to use the max available bitdepth. The number you see is as reported by audio subsystem for driver-SOC edge.
