can help you, link below: _ DVC on--> EQ on--> vol A. _ DVC off--> EQ on--> Vol B. https://androview.wordpress.com/tag/volume-limit/

You can on or off DVC, If you feel is better.

You playing game while listening music (use Poweramp)???. Can SRC android do lower volume.

Audio focus--> -short audio focus change: uncheck. -duck volume: uncheck.

If your file is 16bit-44.1khz, you can try setting: Hi-res output : wired headset/aux: on - Sample rate: 44.1khz - Buffersize : Small - No Equ/tone: check. RESAMPLER: - SoX. - 95.0% - Dither: None. ADVANCED TWEAKS: - DVC : uncheck - Volume levels : system default (16). - Smooth EQ/tone gain: uncheck EQ-TONE-LIMIT : off MISC - Use wakelock: check. - Keep service: uncheck.

You can try to select sample rate in hi-res output. It can fix latency delay.

Hi Andrewilley I have problems playing music with Poweramp v3 (703) on xperia z2. Poweramp has stuttering (lag) after I get the message from the chat app (messeging, viber, zalo ...). Cause due to Poweramp lost hi-res connection when receiving notifications from other applications. The solution is to disconnect and plug in the headset. Please be able to fix this.

703 is lag with xperia z2, when I turnoff display. 704 is auto change from hi-res ouput to opensl es ouput.

704 is best.

I test sox resample with Headphone Fidelio X2 (support hi-res) You can try setup DVC off (in Advanced Tweaks).

Yes, you are right. Because we don't have function "variable rate" in v3. If you want use output hi-res, upsample is soulution in this case.

My device is Xperia Z2, support to max 96khz. I share only information about band pass in Sox to limit distortion. You can upsample to 192khz, If you want.

setup resample with SoX from 44.1khz --> 96khz: sound smooth and clear. -SoX on - Resampler cutoff (band pass): 94.5% ~ cutoff 20,8khz (default 97% ~ cutoff 21.3khz and Sox recommend is 95 % ~ 20.9khz.)

You check output sample rate and sample rate your file are same example: if your file is 44.1k, you check output is 44.1k.

hi andrewilley, Thanks for your feedback, I have test again with fullsize headphone Roland. When I try upsampling with Sox, Sound is better with DVC off--> If We is upsampling, we shouldn't use double DVC. With me, sound is best with setup : no resampling, DVC off ( in audio/ Advanced Tweaks ), Normal buffer size.
