try it with Walkman and this mod

or maybe you can using Player Pro, Neutron or poweramp
[Samsung Galaxy W I8150] Dr.Love:
Please help me fix error "cannot play track" in walkman with Acid v8.0 installed.

Hi [MENTION=4666531]Rizal Lovins[/MENTION],

First many thanks to you and your Acid team for your great sound mod. Could you help me fix this issue ?

I'm using S4 with JB 4.2.2 deodexed rom. I installed Acid Audio v8.0 in this thread (version for Android 4.1 and newer) with clean rom. Then installed walkman engine v8.0 but Walkman cannot play .flac file. It shows "cannot play track" whenever I click play .flac file. The .mp3 files are still played very well.

In changelog of Acid Audio v8.1 for Galaxy device in this thread, you wrote

You can fix bug can't play song or can't play .flac file? But I don't wanna install Acid Audio v8.1 because to me the sound quality of Acid v8.1 is not good as Acid Audio v8.0's.

So could you help me fix the error "cannot play track" with .flac files in Walkman with Acid Audio v8.0 installed? Or Could you fix only error cannot play .flac files but keep all libraries, modded audio files of Acid Audio v8.0 on v8.1?

Many thanks, first.

I installed this on my galaxy 3 running cm7.2 and it is awesome. Just wondering though, due to it being a gingerbread rom, can i only flash the clearaudio+ add on, not the walkman one? Also, will the audiofx widget work with this?

if you can boost sound and keep clear audio quality it will be great for GB :fingers-crossed:

[Samsung Galaxy W I8150] Ahmed.ragab:
if you have DSP installed don't install addon until u uninstall it

and if you use walkman for me it is better to keep it and not install addon
[Samsung Galaxy W I8150] w4nkh4iri:
I don't to install it..by the way,my wonder use pure cm9 eol and just tweak kernel..

so,if i wanna install it,I need to install both or just install dev-host only?
[Samsung Galaxy W I8150] Ahmed.ragab:
I think cm eol has dsp manager so UNinstall it first if u want to install addon if u will keep dsp do not install addon

To our AC!D devs, i think i have found bugs.

When the screen is off and i plugged in the headset , the screen didnt turn on , and suddenly the phone restarted . It happen when i am using another rom before (i forgot what rom and what tweak , kernel i used) . Right now i'm using cm9 final release + kernel honeyx 7up 3.0.88 , with seeder , disabled cpu rendering , and i also use walkman player.

Is it just happen to me or someone have experienced it too?

This is not AC!D bug... This happens to all CM by ARCO. Why? Nobody knows... We really couldn't track the 100% repro rate for that bug. Still, the workaround for this - is unlocking your screen before plugging in headphones. ;)

[Samsung Galaxy W I8150] HumansAreTasty:
As I stated in my previous message, it works without a problem, which means it changes the audio quality and I can configure "the brightness and bass" of the sound from its own equalizer thing. But it doesn't work with all 4.4 roms. So we still need a fully 4.4 compatible version. :)

so we will wait for it ( sorry for off topic question ( how is cyanfox rom performance with you is it satisfied u ? ::)

[Asus  Eee Pad Transformer Prime] Aelemar:
I installed CWM yesterday through Rom Manager to replace TWRP (TWRP kept asking for a password every time I tried to boot into it, and I couldn't do anything at all with it).

Now, holding Volume Down and Power does not bring the Fastboot screen up at all, it simply stays at:

Top left corner: The Device is Unlocked

Middle: Asus "Inspiring Innovation, Persistent Perfection"

That's it. I have read about an "unrecoverable" error, but nothing of the sort pops up.

Fastboot simply is not coming up, at all.

Any ideas what I could do? Or should I just take a hammer to it?
