How To Increase The Volume Of The Kaiser??

its really to low to listen music!! i have the original rom fr of the kaiser help please

Not loud enough, how about the earphones?
Assuming you've mastered the volume slider or jog wheel on the side (see the instruction manual for further details on that) and it's already at maximum, the next step is to change the device you're listening through. I use the Kaisers speaker to output the TomTom Navigator 6 instructions when cycling around with the phone mounted on my bicycles handlebars, thats loud enough for me even in most traffic. If I plug in the original earphones though, when playing music on the train, I can get it very loud (unpleasantly so). If it's just the speaker volume you want to crank up, I suspect thats a hardware limitation of the tiny speaker and you'd risk damaging it even if there was a way to increase the signal going to it. Personally, I'm pleased the speaker isn't 'to' loud, it makes it less likely that yobs will want to create noise pollution with their 'music' from these devices on public transport!

I agree with you the volume is low period, either it be from headphones or internal speaker. Instead of wasting your time like Flying KiWi (dude, whats with your post, you just typing junk to get a post count up?) I will offer some suggestions.
I use TCMP (or CorePlayer) to play mp3's and there's an actual volume booster in the options. in core player to find this option, goto menu, tools, preferences, select page, audio, adjust Preamp accordingly.
Give it a shot, I think you will be pleased..

I Agree TCPMP has an excellent Audio / Preamp volume Increase that works excellent. Sure would be great if someone could create an app that would do the same to anything you use.
I use Resco Radio and the volume is too low at Max. I work in a factory where there's grinding going on with the compressor kicking in every few mins.
I end up having to switch to TCPMP to get enough volume to hear. I've Tried HTC Equalizer / Booster but it does nothing. Maybe someone could tweak it so it Does Work?

Well, are you sure your mp3 songs have been ripped to a good volume? Do they play at normal/loud levels in any other MP3 player (I'm assuming they're encoded in mp3 format) It's no use trying to crank up the volume with HTC Equaliser/Booster etc if your original song files are of low volume/quality...Then you'd have to use a Sound Normaliser/Booster like MP3 Gain on your PC etc to first boost and normalise the volume before you try and squeeze your device for every volume gain you can get...

i owned the htc wisard before and with the bridage_gain_headset.cab i had no pb to fix the volume up but by now i cant listen music without hearing everything around me :'(

I understand your post but I was talking about streaming radio from Resco Radio. Has nothing to do with .mp3 files.

Do you have that .cab? Can you post it? would like to fool with it. Thanks.

this is the bridage

Thanks! I'll let you know how or if it works out.

okay thx

Just one question. What exactly does this .cab do?
Its tiny -- only 1 kb. I installed it but not sure what it does. Does it just kick up the volume / registry setting?
I opened a few media players and it does seems louder but not sure. I will fool around with it more later.
Please Advise. Thanks.

yes change the registry setting..

Apologies, I totally misread your post. I use Resco Radio as well and my volume is OK there and I actually have to turn it down quite a bit...What ROM are you running? Maybe let's start there...I'll post my Resco Radio settings (screenshot) later if that helps...

yes maybe its because of this rom i run the originale french rom from htc...

Hi, I'm just using the Stock Rom TMO HTC Wing. Only thing I've done is change the pagepool to 4mb, which improved things alot. Resco Radio volume is fine except when I'm at work and all the machinery and compressors are running, which is like all day. I just need a little bit more, not much. TCPMP does it with preamp volume boost.
I can change the knob to one that has 11 instead of 10.

Well, you do know stock ROMs have been proved (SPB Benchmarks and others) to perform sub-optimally compared to "cooked" ones in many respects (file transfer speed, write speed etc inter alia)...I'm not suggesting you go out and start "flashing" cooked ROMs just to solve this but maybe a different stock ROM to start with...coz we're really trouble-shooting here to find out if it's a hardware (HTC Wing + resco Radio) or software (stock sound drivers, TCMP application etc) related limitation...

Yeah I hear ya. The only reason I don't wanna flash it is because its Warrantied by T-Mobile for one year. They've already replaced it two times. If I flash it, I'm on my own. After one year is up, yes, I'll start messing with it.
My Old Audiox 5600 worked much better once I flashed it from WM 2003 to WM5.

What about max level via a2dp?

Does anyone know if this affects overall sound volume. I listen to music on my Tilt via A2DP and the sound volume is so low it's almost unusable.

Kaiser/Tilt Ringtone Volume Increase

Hi I was wondering if anyone new how to increase the ring volume on the Tilt. I did a couple of extensive searches and all of them came up for either older phones or different phone models. Also, I read somewhere that each HTC registry differs in some manner.
I would greatly appreciate it if someone can point me in the right direction to this fix.
I would also be interested in louder speaker phone volume too.
Thank you in advance.

get into your registry...HKEY_CURRENT_USER/control panel/sound catagories/ring. Here you will find2 setting at the bottom..."InitVol" ans "Speaker". Open these both, and change the "value" number higher than what you show. I have both set to 15...initvol was at 5, speaker was at 8 when I first got it. I also opened up the "alarm" file at the top of the tree and made sure that speaker value was set to 15 as well.
Now...I can hear it fine, but the dif. is pretty small. I read about this edit, but never heard back from the guy that posted it. I can't say for sure this is any kind of pro-approved method, as I am quite new to this phone/system myself. I had been hacking Motorolas till I got this a few weeks ago. I have no idea how high that value can be safely pushed, and by the looks of the device..the speaker is pretty small and weak anyway. Hope this helps..be careful..lol. Blow that lil speaker and you won't be hearing a thang!

Do a search for TCPMP. It is a media player. On the options>settings>select page> equalizer tab. check the "enabled" box and then "slowly" slide the "Pre-amp" slider to the right... trust me it will play louder!!!

So that volume tweak above is for ringer volume, what about external speaker volume (e.g. play music or hands free)?
What about the internal speaker volume for hearing the person on the other end of the phone?

I'm another newbie who'd like to know how to get to the registry...HKEY_CURRENT_USER/control panel/sound catagories/ring. after I already installed PHM RegEdit.
Thank you.

Thanks works like a charm i have a tilt with 6.1

I have known about these reg hacks for quite some time but they never work for me
i checked my dec values with this new ROM and my intvol was set at 0 and my speaker was at 1. i put them both to 5, the sound actually got lower but then higher, and lower then higher. weird
set both to 15..don't really notice a difference..

It's not that bad in Kaiser though. I used to have Eten M600 which was worse in many aspects of sounds volume, esp. loudspeaker. What we did was to replace the ril_gsm.dll with a patched one plus some reg hacks.
So maybe in this case if the reg hacks simply don't work or keep reverting back to its original value, then there's more to do than just registry. Just my 2.01 cents.

does anyone know how to increase the sound for incoming message?
please advise and thanks for the share

hack to increase speakerphone volume?

Are there any hacks to increase the speakerphone volume?
I was rocking Resco Radio and its plenty loud. But the speakerphone is sadly quiet. Any recommendations are greatly appreciated.

Mine is quiet too, but the sound is already cracking if I use the speakerphone. It's unfortunate that the quality on the speakerphone is under par.
Does yours crack?

What about hardware modifications? Maybe two speakers. There is room for it.

Cool, let's get some xenon flash in there too while we're at it. Looking forward to when you post pics of that, Paitor hehe

I too want the speaker volume to go up. I dont really bother about the music playback but i want the phone to be loud when it rings when a call comes in. I donot realize the phone is ringing in my pocket and end up missing calls.

I installed the optxperiabeta02.cab from this site http://ixperia.ru/soft/winmobile/51-opt-xperia.html as it was mentioned on another thread about increasing volume...

Xperia X1 Full Sound Boost Tweak

Well this is a simple tweak just the audio boost as a cab overwrites the audiopara3.csv and audiopara3_xc.csv to two new ones that are tweaked to full boost. Hope you like your new boosted sound.

anyone try this already?
Is it going to make the sound louder?

It has the audiopara3_xc.csv from optxperiabeta2 and audiopara3.csv edited by me to a full boost, only thing it does it overwrites this files, if you are not shure, make a backup of this two files first.

Very good !! I will try and amazing ... it boots sound in my Xperia X1.
Now i am use ROM : Touch X NUT, 6.1 !!!
Thank you again !!
Some one can test, if some one afraid, can backup 2 file Owner Topic said ( C:/Windows/ ) and can try to install --> Boots about 50% sound !!!
( I'm in Vietnam so English is bad )

i d installed optxperiabeta2. which had boosted the sound a lot. now i intslled this, sounded no louder than before for me anyways

works, thanks. Anyway its enough for me

will this work for Xperia x2? can someone check?

Hey it work for xperia x1i, install it since 28/3. Not problem for me.

X1 hardware will be having problem if I install?
read somewhere the optxperia did some damage to X1 hardware. Is it true ?

how to install those files?

hi mate,
I've been using optxperiabeta2 for almost 1 year now and I never experience any hardware problem with it.

will this boost in call sound (headphone and loudspeaker) or just ringing sound....

hey works absolutely fine. thanks, this has really boosted my audio.

infact it is fantastic since the audioboost has happened with no effect to clarity. the clarity remains good if not better.

And the question again: what will this boost? Phone volume, ring volume, speaker volume, loudspeaker volume?

Thanks a lot! it works on my X1!

you should cafefully to use this tool!
when you use this tooth, i gave you a advise about problem of speaker. You shouldn't turn your volumn to 100%, it can make your speaker break down. it's my own experience.

I've used optxperiabeta2 before but it has also caused my vibrate to go crazy, vibrating like hell. So i'm not sure if there was some issue with my phone just the program itself. So i've never used it since that incident. But definitely makes the volume louder though.

Its realy perfect

Boost Output Volume on 6.0

If youre like me and you like listening to your music with good headphones and want to feel that bass rumble in your head, you might have noticed that with the update to 6.0 (In my case to B565) the output volume might have gone down considerably and that now the max volume isnt just enough to make you eargasm. So i researched a lot and found out that the max volume settings are set in some .xml files located in /etc and /system/etc but the thing is that with huawei phones we dont just have to edit a single .xml file to raise our max volume, we have to edit a whole crap ton of them depending on our region, vendor, model etc.... So instead of having to open all those files and edit just the correct string, i found out that AlsaMixer (Available on google play) works just fine with out devices!! I also found out that the max output on 6.0 is stuck at 80% dont know why.
So, to get your 20% of max volume up, all you have to do is open AlsaMixer (or all those other .xml files if you like doing things the hard way ) and edit the lines:
-HISSC_SMT_HSL_GAIN (this is left headphone gain)
-HISSC_SMT_HSR_GAIN (this is right headphone gain)
Their default value will be 12, just go ahead and set that value to 15 which is the max value and enjoy your new volume
NOTE: There are tons of other strings you can edit to increase output of speaker, earpiece, etc...etc... but since I didnt need to increase these I didnt take the time to find out their variables, but if youre interested on increasing the speaker volume just open the .xml files and go to speaker and find the gain variable and change it with Alsa.
Hope I made your day

You might be able to do that with Tasker or a similar app. ALSA is only in charge of the sound.

tested and working good. only thing i noticed is that after i modify the value it wont save for the next time i use the player so i have to edit and apply again.
really thanks for sharing

So looking into AlsaMixer, this is an app for a rooted device. Is there any alternative methods? I just got my phone finally back up and going again after an IMEI loss and am a little scared to do anything further in the system like that.
Also the fact that the description on AlsaMixer doesn't say anything about supporting MM... Has the had any issues for you?

I dont think there are any other *effective* methods out there that dont imply rooting your device or something of that behaviour sorry. And yes it does support it, at least for me even though it says nothing.

You solved what? We already know about dolby atmos, but this is different.

Yes Dolby Atmos gets a little better sound quality than stock. But it doesnt boost output volume in any way or form. For that the only thing that works is editing the ALSA setting but for the speaker I dont know which string you have to edit because as i said im not interested in listening music through my phone speaker, i was just interested in boosting the volume from the headphones which I thought were too low. Anyhow I discourage everyone who wants to boost their speaker higher than stock, as this phones speaker sounds pretty high, even too high sometimes and you could risk damaging the speaker or braking it.

is it even possible to boost without root? i guess not. but app can probably deliver higher sound.
for root users theres usually a xml file in system/etc i can't tell which one it is since i'm first time huawei user but if u got root why not use viper4android it boosts the volume like

I would like to boost the volume only for my headphones. Which xml files should I edit? I am thinking of using a file explorer to edit the values on OP for this.
Thanks in advance.

Use the playback music controls xposed module.Its awesome and you can also change tracks using volume buttons if you like. The autoplay option is in the settings.

I've found out how to boosz permanently, I guess... System/etc/audio/hissc/mixer_paths_ALICE.xml
Open it with a text editor, and change HISSC_SMT_HSL_GAIN + HISSC_SMT_HSR_GAIN from 12 to 15.
