Enabling speakers with headphones plugged in? (solved)

[deniska]

Does anyone have any ideas on how to achieve it?
Apparently, it's possible in Talkman..

[adrahil]

Hi!
I need to check it, but I have an idea on how to do it ;)
I will post a snippet of code in a few hours. :P

Cheers,

Adrahil

[deniska]

this would be super!

[Brunni]

Yes, would be great.
Btw do you know if there's a way to know whether the headphones are plugged in or not?

[dot_blank]

Code: Select all

if( sceHprmIsRemoteExist() ) { // check if remote is connected
    if( sceHprmIsHeadphoneExist() ) // check if remote + headphones are connected
    // do your madness
}
else
if(sceHprmIsHeadphoneExist() ) { // check if headphones are connected (WITHOUT REMOTE)
    // do your madness
}
else
if(sceHprmIsMicrophoneExist() ) { // check if microphone is connected (WITHOUT REMOTE)
    // do your madness
}

[Brunni]

Oh yesssssssssssssss so cool! I've gotta try this :)
This would make the psp a great audio player for silent rooms if we could pause the audio output when the headphones are accidentially plugged out ;)
Thank you veryyyy much :)

I keep getting problems with the code :/ Albeit the library is here, it will not link correctly. Time to update toolchain, i guess.

Can you post the code, so perhaps other people will be able to compile/link it?

if( sceHprmIsRemoteExist() ) { // check if remote is connected
    if( sceHprmIsHeadphoneExist() ) // check if remote + headphones are connected

if(sceHprmIsHeadphoneExist() ) { // check if headphones are connected (WITHOUT REMOTE)
    // do your madness
}

Just "FORCING" ;) them to return 0 will do the job?

[deniska]

it appears that chopping off the tip of the audio plug connector does the job.
the serial port is still on while the speakers are not muted...
just make sure that you leave the other 2/3rds intact...

[Brunni]

I'd like to thank dot_blank again, I can now automatically display a message when the headphones are plugged out. The game is paused, the sound muted, and you can select whether you want to disable sound or keep it playing (on the speaker). That's very cool :-)

That's what I call a dirty hack!

Playing music simultanously via both the PSP speaker AND the headphone jack is IMHO *very* dangerous for the PSP hardware, as this might easily surcharge the audio power amplifier/output stage of the PSP. The result would be a PSP without ANY music.
If you want a pull relief for the audio jack, I suggest you simply glue 2 Velcro strips onto your PSP.
If you want be able to use both headphones and loudspeaker at the same time, I'm afraid this won't be possible without any soldering inside the device... Anyhow, I don't see any good reason for using both at the same time...

//EDIT: @Deniska: If I understand you right, you simply chopped off the connector for the left audio channel.

The way the speakers are disabled when you plug your headphones in is quite simple: there's some sort of "button" (AFAIK a tiny little convex round metal plate under which are 2 contacts (one outer circle and one in the middle) which are connected when the tip of the plugged jack connector presses the plate onto both contacts).

[deniska]

Actually, I only need the sound through the speakers so this hardware trick works fine for me... Basically, I just want to be able to use speakers while using the serial port for gps receiver communication...

Why the pointless quote?

Surely you realize that Deniska is playing audio through just the speakers (even though his headphone connector is in place) and so that quote is irrelevant.

Not that it matters either way. I strongly doubt you can damage the PSP's audio output stage by doubling the load. It's would be no different than plugging in a set of very low-impedance headphones, and Sony has certainly thought about that.

Oops.
I meant to add my own words to it and agree with you.
ie. they are big words for a tiny amplifier,
and to add my own finding (have a spare brick):

There is a metal lever at the far end of the socket as already figured,
it is normally closed. Since I know this is on the left hand side of the
socket when looking into it with your PSP screen facing up,
you can avoid opening the switch by shaving only the left side of the tip
terminal. It may also stay connected, and I don't know what the result
of this will be.

on DIY serial plugs the headphone plug can be an effective switch
by rotating it 90 degrees, and the headphenes still work otherwise.

Thanks, but do you know a similar command for the mic?
I have seen the original PSP input recording app detects the mic.

mic in the headphone port?

[Art]

yes,
I tried the obvious:
sceHprmIsMicrophoneExist
but doesn't work.

EDIT... oh, of course it is. all of these are defined in PSPHPRM.h,
but the lib has to be included ;)

    if( sceHprmIsHeadphoneExist() ) // check if remote + headphones are connected
    // do your madness - DONE
}
else
if(sceHprmIsHeadphoneExist() ) { // check if headphones are connected (WITHOUT REMOTE)
    // do your madness - DONE
}
else
if(sceHprmIsMicrophoneExist() ) { // check if microphone is connected (WITHOUT REMOTE)
    // do your madness - DONE
}

It made Absolutely NO difference!

All three Return 0 but still no sound! :(

Guess, Adrahil is our LAST hope.

That code simply checks for the remote/headphone/microphone. It was posted in response to Brunni's question on how to tell if anything is plugged in.

Btw do you know if there's a way to know whether the headphones are plugged in or not?

So it has nothing at all to do with enabling the speakers with the headphones plugged in.

That makes it CLEAR! :D

Actually, the latest version of mapThis (0.520) enables speakers even if the phone plug is in (no cutting of the audio plug tip required).. The code can be found here: http://www.dcemu.co.uk/vbulletin/showthread.php?t=79825

The code works on ta-79 and slim psp (that I have at my displosal) as long as it's ran under m33 3.xx firware (tested with 3.52 & 3.71)

siogps.h's functions do that?

Wow. Great work!

I'm finally able to confirm that Talkman does it, but I guess it's already sorted.
Talkman would have to be the most unfortunate PSP title.
It doesn't get anything right.
