reg key!

is possible for you to put in only one topic All the best reg key adjustement?
i'm a newbie but i would learn quikly..
many thx!

Try to use usenet instead of this forum. It's a little bit illegal

I think Bubu try to search Registry key and not Registration key :wink:

You are right. I'm sorry
In that case:
Dunno if you've all seen this before but you can speed up your JAM by doing the following:
1) Go to HKEY_LOCAL_MACHINE\SYSTEM\GDI\GLYPHCACHE
2) Change the value of 'limit' from 8192 to 32768
3) Soft reset.

I did it to my JAM...no problems so far. Does seem to be a tad faster in loading apps...remember to backup before messing with Registry values!

How to lower the microphone gain?

I need to lower the microphone gain.
My audio codec is clipping becouse of incoming PCM samples saturated from
the mic. I don't need AGC becouse it doesn't work well with my app.
I just need to manipulate the mic gain via software.
Is there a way to do it? I'm using waveform audio api ti capture voice.
Actually the gain is too loud !!!
Thanks.

Anyone knows?

OK, I don't have the answer. But since no one is responding I'll try to give a few ideas that might help.
First, I have a hp6315 and an apache. Under settings, they both have a utility to enable/disable AGC. The ipaq's utility is labeled "ipaq audio" if you disable agc, you can then configure the microphone gain. This gain is stored in the registry. I think searching for gain or audio will find it. The apache doesn't have this. searching for audio, gain, wav, volume in the apache registry doesn't find anything that looks like microphone gain. I guess this is a "value added" thing from hp. But you could try searching anyway.
Then there's the mixer API. This is the way that user level apps are meant to control the audio. Works great on the desktop. Use mixerGetNumDevs() to find out how many devices you can control. On the h6315 mixerGetNumDevs returns 0. I haven't tried the apache, but I can remember a few years ago reading that many (most?) devices return 0. Oh well, hopefully you'll have better luck. However, there are two mixers that are implemented on the pocketPC the question is how to access them.
see this link for info on the mixers
http://blogs.msdn.com/medmedia/archive/2007/01/12/what-do-you-mean-by-mixer.aspx
Here's a link that shows the relationship between the mixer api and the other mixers, wavedev2 mixer, and software mixer.
http://msdn2.microsoft.com/en-us/library/ms923709.aspx
You'll notice that the the mixer api interacts with the mixer in the device driver not the software mixer in the WaveAPI.dll. You'll so notice that this section on audio drivers has pages for MDD/PDD drivers and Unified Audio Model (UAM) drivers. Platform Builder for WinCE 5.0 comes with a sample for each of these model drivers. Both models handle WAV_IOControl Messages. There are two types of messages, IOCTL_MIX_MESSAGE for the mixer, and IOCTL_WAV_MESSAGE for the rest of the driver. It looks like these IOCTL_MIX_MESSAGE are the way the mixer API controls the mixer. In the MDD/PPD sample they can be used to set WPDMX_MIC_VOL and WPDMX_LINEIN_VOL. In the UAM driver it's AC97_MIC_VOL and AC97_LINEIN_VOL. Perhaps sending the right IOCTL will solve the problem.
This blog entry
http://blogs.msdn.com/medmedia/archive/2007/01/03/windows-ce-audio-driver-samples.aspx
seems to say that a wavedev2 sample is available now. Also, while the WinCE 5.0 page above only metions two models the corresponding wince 6.0 also talks about wavedev2. I suspect if you got the current version of platform builder for WinCE 6.0 (trial version is free) you would have get the sample code for wavedev2, which is likely to be the best documentation of how this works. Amazingly, the drivers aren't that hard to read.
Both of the functions waveInMessage() and waveInSetProperty() are available to user apps. Hopefully both should be able to change the microphone gain if you can set the parameters properly. While most of these things are about windows CE, I think most (or all) apply to windows mobile 5.
Windows mobile 5, likely uses wavedev2 devices not MDD/PDD or UAM drivers.
Another interesting page about wavedev2 audio is here:
http://blogs.msdn.com/medmedia/archive/2007/01/04/the-wavedev2-gainclass-implementation.aspx
If your able to succeed or even learn more, be sure to post it back here.
I said a lot so I probably got something wrong. Anyone, please feel free to correct anything.

mixerGetNumDevs() returns 0 on my device
I can't find any registry entry which suggests microphone gain manipulation.
Perhaps i just need to send a waveInMessage properly.
I'm getting confused, should i implement a driver for this?
How do i know what kind of driver is running on my device and what messages
does it accept?
Thanks.

i think this may be what you need(?)
use a registry editor, (phm do a good free one)
hkey_local_machine/software/htc/audiogain (and audiogain 0 and 1 and 2)
try playing with the settings in there, soft reset to take effect

I don't have that keys on my HTC, should i create it?
Do you mean audiogain0 audiogain1 audiogain2?
Thanks.

see the attached screenshot, if you don't have those settings to adjust, a similar/same question was asked last night in a other thread, with different answers here
http://forum.xda-developers.com/showthread.php?t=306655

Looks like the cab file from the link provided by bbobeckyj just sets those audiogain registry settings. I don't have those settings on my apache. I don't think adding will help, but "you never know".
If you want to use waveInMessage() or waveInSetProperty() search for them at microsoft. You'll find there are a few parameters that you don't know. Read though the sample drivers that you can get with platform builder. See what values they expect, and which one cause them to change the microphone level. Try calling the function with values from the sample driver. While there is no guarantee that they use the same values, it's like that they do. I would start with the wavedev sample.
I don't know why microsoft doesn't seem to allow access to the source without agreeing to download all of platform builder, but it looks like that's the only way to get it. You can download the trial version for free. The source often helps if your trying to fingure out how something really works.

Uhmmm, i havn't found any download link about platform builder for windows CE 6.0. I've only found the 5.0.
Should't the trial be free?
Thanks.

I need to fix audio gain in my Itel Experience Phone (Windows Mobile 6.0 Pro)?
Please help.

I need to mute mic while on a call. Anyone has a idea of how may i do it?
Thanks

moved to the right forum, please post in the correct forums.

More precise volume control app?

At the moment i can only use the standard windows mobile 5 step volume control, and this is VERY annoying.
Like in windows media player you can change the volume from 0 to 100 with steps off 1% at the time..
Is there such app that does this for the sytem/ring volume?
Because when i'm now listening to music and it's not loud enough, i can't put it louder, because it's going REALLY loud then.. because i have only 5 steps

Using the WinMedia vol control in other applications
If you are willing to do a reg edit
here is a copy of someone else's post I saved
wish I could give "Pete S" more credit
________________________________
Using a registry editor (I use Total Commander), navigate to
HKLM\Software\HTC\VolumeOverlay\3rdPartyAPClass and you will see a list of apps which use the slimvolume control. You have to add keys (new folders in Total Commander) for all the apps you want to add.
Under these keys you have to create a String value containing the Window Classname of the app. You can get these names using a program like FdcSoft Task Manager v3.1.
I've listed a few of the common ones below to save you the time.
Create a Key: "Nitrogen" Create a String Value called “ClassName” with value "CNtgWndMain"
Create a key: "CorePlayer" Create a string value called "ClassName" with value "wCorePlayer"
Create a key: "Opera" Create a string value called "ClassName" with value
"Opera_MainWndClass"
And so on. Take care to get caps and lower case correct, and don't include ""s. If you get the window class names wrong, don't worry, it just won't work till you get it right.
The settings take effect immediately, no need to restart.
PS: If you're not confident editing the registry, best not to do it. If you do, take great care, don't accidentally delete any keys!

Or if you use TD2 tools (available here on xda)
It will automate the entire regediting process and allow you to add
the 15 position vol control to other APs just by
"opening them and inserting the stylus"
Very simple to do and TD2 Tools has many other useful and powerful features
Hope that helps you or gives you some pointers to get started
in a nut shell
Yes! you can do exactly what you ask and its pretty simple
with either a reg-edit or automated with another free program
(look for Gaz TD2 Tools for WM 6.5 (Release 2c).cab)
KJL
BTW I've reported a bug with the slim sidebar control in the Tess 4.2
ROM so if your using it you might need to wait for a software fix
to use the above

workaround!!
Use advanced configuration tool
goto HTC audio manager
set music player volume to 50%
Now the music isn't too loud and the steps are smaller !!
greatings Nico

I well understand that TD2 tools is only for W6.5, but is your manual procedure to create et reg key OK with W6.1 ? I don't find the 3rdPartyAPClass in HKLM\Software\HTC\VolumeOverlay. How can I do ? Thanks in advance.

I use TD2 Tools with the standard WM6.1 ROM that HTC issues. I have version 2.0.3552.42948, release 2a.

The registry edit works for 6.1
If you can't find "3rdPartyAPClass", I presume you have "InhouseAPClass"? You could try putting the new entries in there instead.

In fact, TD2 tools can change these parameter only from the 2c version. But, I succeed in making manually the key as explained before. But unfortunately, no change in the volume behaviour.
For me (and it seems I not alone), the main issue is the hard button vol+ and vol- which are not able to change the volume level les than 25%.
Thanks.

Still looking for something like this

Instead of using the classical VolUP and VolDOWN buttons, just tap on the Volume bar to select a more precise Volume percentage.
Am I wrong?

Sorry for double posting.

Bluetooth A2DP bitpool

Hi
Any ideas on how to adjust the a2dp bitpool settings. I am coming from windows mobile where this was easy to do in the registry. The stock bitpool seems to be 32 as per the logcat readout below. This is coming from an Evo 4G:
W/BTLD ( 1677): ### :: codec open ::
W/BTLD ( 1677): ### mtu 512, 660 bytes/frame, bitrate 229, nbr ch 0, freq 240
W/BTLD ( 1677): ### alloc : 3, blk len 240, chmode:15, bitpool 32:2, subbands 12
the sound is ok but could be better.
Another interesting part of the logcat is:
V/A2dpAudioInterface( 136): setParameters() bt_headset_name=DRC-BT15;bt_headset_nrec=on
E/AudioHardwareQSD( 136): setParameters() bt_headset_name=DRC-BT15;bt_headset_nrec=on
I/AudioHardwareQSD( 136): Using default acoustic parameters (DRC-BT15 not in acoustic database)
(I wonder what the acoustic database is.)
Any suggestions would be welcome. I did search around and found nothing easily implemented. Also nothing on the market.
Thanks

I want to know the exact same thing and not ready to accept that WinMo is superior to Android in any way...

I just found this page here which discuss some terminal and backend files in OSX for modifying these settings. Is there any similar file or terminal command we can do on our own unix based systems?

I have spent the last couple of weeks working on this and have come up with nothing. But I am not a programmer. Hope someone knows where to make the changes.

any update on this?

I am no programmer in any way, but I would realy like to know the outcome of this thread because it's been bugging me since I bought my Desire. I realy can't stand the loss of sound quality when listening to music on a bluetooth headset with my sennheiser headphones(HD215) connected.

I was wondering about the same thing. I used to tweak my WinMo Bitpool and samplerate. Any way to do this on Android?

I have been following this too. There must be a way to edit this somehow!! The a2dp quality of the evo/desire is awful! Must find a way!!!

I'm also disappointed in the audio quality on my Desire. I use my phone to listen to music in my car or mobile speaker via bt. But there are many tracks with high frequencies (or frequencies in some range), that causes some really disturbing clicking noise! Which I don't had on my Nokia N82 and SE K800i.
This really annoys me, and I consider to change to a different phone if there will not be a solution I'm currently using the original HTC firmware/radio, because I haven't rooted my phone yet. Is it possible that flashing a different radio will help?
I'm not sure if this is caused by the bitpool setting.
I will try to capture/upload some fragment with this clicking...
Edit: The microphone isn't good enough to record the clicking, but this fragment illustrates it very well (the clicking was actually in the track itself, but it sounds almost the same):
fragment (mp3)

Has there been any kind of an update on this one? A fix or a setting that could be changed?
I'm thinking of buying a Desire Z, but I will certainly stick to my ancient Touch Pro if the A2DP quality on Android is as bad as you all say. Bitpool of 32 is unlistenable, and I can't believe that neither Google nor HTC care about it.

Now that Cyanogen has fixed this in their ROM, I don't understand why no one has released a method for people not running Cyanogen.

So it has been fixed? What bitpool does that ROM run? I can't seem to find any info :S
And will they make a ROM for Vision with that fix?
I know I've got stupid noobish questions, but I'm completely new to the whole Android story and I haven't used these forums for ages so I'm quite lost atm...

CM6 is running 53

Thanks for the info

I'm having issues with an epic I just got (luckily in the 30 day return period). The a2dp audio sounds like garbage. The a2dp audio on my touch pro stock (before tweaked) was much better.
This could be a dealbreaker for me.

This is good news, but surely Mr.Cyanogen can pass on his method to Cotulla or one of the other primary Android Devs.... Hmm!

Any news on this? I flashed to Cyanogen 6.1. A2DP sounds much better. I now have mulitple exchange accounts working. The few issues are the Expensify receipt image capture does not work, 4G and HDMI also (know issues). I hope someone can find a fix for this.

I had a look at the bluez source code posted on HTC's developer site and I believe this is where the bitpool value is being set:
Code:
supersonic_bt.zip/external/bluetooth/bluez/liba2dp.c:
static uint8_t default_bitpool(uint8_t freq, uint8_t mode)
...
case BT_SBC_SAMPLING_FREQ_44100:
switch (mode) {
case BT_A2DP_CHANNEL_MODE_MONO:
case BT_A2DP_CHANNEL_MODE_DUAL_CHANNEL:
return 31;
case BT_A2DP_CHANNEL_MODE_STEREO:
case BT_A2DP_CHANNEL_MODE_JOINT_STEREO:
return 53;
default:
ERR("Invalid channel mode %u", mode);
return 53;
}
Changing the "return 31;" to "return 53;" and recompiling -or- hex editing the binary liba2dp.so on the phone ought to do the trick.
The same code block also appears in ipctest.c, pcm_bluetooth.c, sink.c, and source.c, so one or more of those files may also need to be modified.
I just got my Evo and I don't know enough about it yet to try this myself, but if someone else is able to then I think we'd all appreciate it if you could give it a shot. (Not all of us are interested in running a custom ROM just to fix this one problem.)
Edit: Another way may be to just force your desired min and max bitpool settings in the function bluetooth_a2dp_init():
Code:
cap->min_bitpool = min_bitpool;
cap->max_bitpool = max_bitpool;

Disregard that last post of mine. I had another look at liba2dp.c as well as some D/A2DP log output. All of the log output I could find posted online contains "channel_mode: JOINT STEREO", which according to default_bitpool() means the "default" bitpool should be 53. I originally thought the problem might be the bitpool setting of 31 referenced in that function, but I could not find any log output that contained "channel_mode: DUAL CHANNEL". (It shouldn't be too hard to verify this.)
So why is a lower bitpool value used? Look at this code snippet from bluetooth_a2dp_init():
Code:
min_bitpool = MAX(MIN_BITPOOL, cap->min_bitpool);
max_bitpool = MIN(default_bitpool(cap->frequency,
cap->channel_mode),
cap->max_bitpool);
cap->min_bitpool = min_bitpool;
cap->max_bitpool = max_bitpool;
The max_bitpool value is set to the lower of 1) the "default" bitpool and 2) the max bitpool reported by the audio sink (ie. your headset). If your headset reports a max bitpool of 32, then that is what will be used since it is less than 53. My understanding of the bluetooth spec is that audio sinks are supposed to accept bitpool values higher than 32 in order to support up to 512 Kb/s audio. Lower bitpool settings are more reliable, though, so perhaps that is why many headsets are configured to report artificially low values.
The actual bitpool value used is simply max_bitpool. See bluetooth_a2dp_setup():
Code:
data->sbc.bitpool = active_capabilities.max_bitpool;
The a2dp code isn't set up to take bitpool parameters from a configuration file, so liba2dp.c will need to be modified and recompiled. Possible quick fixes would be to change the "max_bitpool = MIN(" line to "max_bitpool = MAX(" or to manually set your desired bitpool value (ie. "data->sbc.bitpool = 53").

Hi,
I just want to say that since unfortunately my programming capabilities are close to non-existent I'm afraid I'm not able to provide much actual help in solving this issue but i highly appreciate that there are people who are looking into this and trying to remedy what Android OS designers and phone manufacturers neglected. I've been using A2DP headsets for the past 3-4 years with Nokia E51 and E52 phones which provided very good sound quality virtually indistinguishable from a cable connection and now after buying a Samsung Galaxy S phone I'm terribly disappointed at its A2DP performance comparable to 112kbps MP3s with even the highest quality sources.
I own three different A2DP headsets manufactured by Sony Ericsson, Nokia and unnamed Chinese labourers respectively and a set of quality IEM earphones plugged into quite good and relatively trained ears. Since A2DP support on both Nokias and a Samsung Blackjack I owned shortly (and let go of just because of its pitiful A2DP performance) has not always been perfect I know a thing or two about how A2DP works and performs. So if there is anything I can do to help regarding testing, preparing and submitting logs etc. just let me know and I will be very happy to help if that's what is needed.
Thanks!

[Q] Registry Key for SMS Recipient Limit

Has anyone found a registry key that controls the setting of maximum number of SMS recipients? Having to set up multiple groups due to the arbitrary carrier-"supported" limit of 10 is a bit absurd.

I may have found something on this myself:
