A2dp
 
In the post describing how to install A2DP on OS2007 its been said that its a simple config change to get A2DP to work on OS2008, now i've changed the one i think it is (Audio.config in /etc/bluetooth/) but there isn't the a2dpd binary installed and the it won't connected to the paired bluetooth headphones. Has anybody succesfully got this to work yet or now of any instructions on how to do it. Thanks for anyboy who has this info.

Re: A2dp
 
You still need the a2dp binaries and something to use them (mplayer, Kagu, etc.)

Are these available for OS2008 yet?

Re: A2dp
 
Ahh ok, somebody had said it was just a config change, if thats the case ill look at tring it out tonight as they shouldn.t need much changing to work on os2008 as there low level and not effected by the gtk and hildon changes.

Re: A2dp
 
That someone would be me (among others). ;) I'm relatively confident that with the changes made to bluez between OS2007 and OS2008 A2DP support is now included by default. AFAIK, all we need to do is uncomment the last two lines in /etc/bluetooth/audio.conf. Then to use A2DP all we should need to do is use any player capable of outputting to ALSA and select the "bluetooth" ALSA device. The problem I'm running into is that I can't seem to find any player for OS2008 that supports ALSA. MPlayer for OS2008 seems to not have the alsa audio out built in and mpg123 appears to be OSS only. Any thoughts?

Ah, I thought Serge had enabled ALSA out on mplayer (certainly he had with the previous version).

Re: A2dp
 
Nope. I'm sure it was enabled in the mplayer for OS2007. I double checked after you posted and here's what mplayer has to say for itself:
Code:

~ $ mplayer -ao help
MPlayer 1.0rc1-maemo.22.n8x0 (C) 2000-2006 MPlayer Team
CPU: ARM
Internet Tablet OS version: RX-34+RX-44_2008SE_1.2007.44-4_PR_MR0

Available audio output drivers:
        esd        EsounD audio output
        gst        Gstreamer audio output for Nokia 770
        sdl        SDLlib audio output
        mpegpes        Mpeg-PES audio output
        null        Null audio output
        pcm        RAW PCM/WAVE file writer audio output

~ $

That looks like no ALSA output to me. I guess I should poke at Serge.

Re: A2dp
 
Yeah thats what i got, the old a2dpd binaries work after a bit of tweeking (one of the libaries has changed but after putting in a link it worked fine) but yeah the little problem with mplayer put the plan into the bin.

Re: A2dp
 
So does AD2P work with OS2008? Does it work with Kagu? Canola? UKMP?

Re: A2dp
 
it *should* work. i ended up installing the .19 release of mplayer and it had alsa support, but it seems like my headphones had gotten paired to the tablet in the headset profile and didn't/couldn't change to the a2dp profile. i'm trying to dig into hcidump to see what's going on but i'm not that familiar wwith bluetooth at that low of a level. any ideas appreciated...

Re: A2dp
 
Currently no, im looking at compiling mplayer to get alsa support but im not sure thats all it needs, i have an incling that a2dp has actualy been compiled out of bluez for os2008
