    I explain how I did, so you can try and share your experience:

    1. copy the file /var/root/Library/Preferences/.GlobalPreferences.plist to your computer using your preferred method.
    2. convert the .plist to ascii (you may use this: http://140.124.181.188/~khchung/cgi-bin/plutil.cgi)
    3. open the new file with a text editor and look for the following section:

    <key>com.apple.audio.CoreAudio.DefaultInputDevic e</key>
    <string>Baseband input</string>
    <key>com.apple.audio.CoreAudio.DefaultInputDevice. actual</key>
    <string>Baseband input</string>

    and change <string>Baseband input</string>
    by <string>WM8758 Input Device audio0</string> in both places.
    4. overwrite the file inside the iPhone... sorry, inside iPhone and restart iPhone
    5. install touchmod sip client If you have not done it yet
    6. IMPORTANT: before running the sip client you have to plug the headset. The sip client will only work with the included white headset.
    7. Dial
    8. start yelling... yes, it works but it seems like the default input volume of the iPhone is just horribly low.

    It would be nice to have more people tinkering about this problem with the record volume... there must be a default value settable in some .plist somewhere. I have a candidate /var/preferences/com.apple.audio.DeviceSettings.plist, but I have modified the <real> values for the input device but nothing changes.

    Ah, something else that some people may like... with this hack, if you use the recfile program in touchmods.net while in a regular cell phone call, the conversation is recorded in the output file ... actually, you will only hear the voice of the person in the other side of the line, since yours will be extremely low .

    A+,

    Gusano.

    Thanks Gusano, this is great news. I have been waiting for some progress with this for a long time. I'll check tonight and report. I recall with an earlier firmware there was problems with low speaker volume and there was a plist hack for that. I'll check if I can find mic volume settings. However, if it VERY low volume it makes me wonder if there is a fundamental problem with this method.

    Btw, does this hack affect any other things on the iPhone, like normal mobile use?

    If by white headset you mean the regular iphone headphones, then it must be the case that like any decent handsfree headset the input from the microphone is normalized on the phone. I doubt the boost is stored in a plist as the phone constantly adjusts the input level from the white button/microphone to keep up with varying distances from the mouth during a call.

    I am not following this subject very closely (altough I'm very interested in a SIP client) but here's a stupid question. Since the problem right now seems to be accessing audio inputs why don't you ask for help from those that wrote say that voice notes app or lately the Listen app? Or are all of these apps using framework routines that record straight to a file ?

    I can confirm gusano's method is working, headphones do work but volume is low. (iPhone 1.1.1)

    Hi there,

    If by white headset you mean the regular iphone headphones, then it must be the case that like any decent handsfree headset the input from the microphone is normalized on the phone. I doubt the boost is stored in a plist as the phone constantly adjusts the input level from the white button/microphone to keep up with varying distances from the mouth during a call.
    Yes, you may be right. The best way would be to control the input level directly in the sip program. I will contact the touchmods people to let them know.

    In the meantime, I have noticed that if you start a song with the iPod application, pause it and then switching to the sip client, the input volume gets a little bit better... hopefully not just my imagination..

    Ah! there is something else, Erica's listen (and I guess voicenotes, must be the same case) do not work if this hack is enabled. She must be using the default input device so the song will be recorded only via the microphone in the headset, since the volume is way too low, no song is found.

    Keep in touch(mods)!

    Gusano.

    Yes, that's exactly the case, see
    http://variogram.com/latest/?p=24#2

    The CoreAudio routine just allows recording into a file. Apparently real-time audio-in is more difficult to do.

    And presumably Gusano's hack (as great as it may be and it sure is a step in the right direction) would inhibit all apps that use the CoreAudio functions.

    Which means that for example Vnotes will not work anymore?
