---- N800, latest os2008 ----

Results: A2DP works... But not very well. I've been tweaking with buffer sizes and such for a while with no apparent change (though I have no way to verify what the buffer size actually *IS*, as depending on the initialization function used, it could be entirely ignoring my settings).

If anyone wants to do testing, follow the instructions in Johnx's first post in this thread: http://internettablettalk.com/forums...ad.php?t=13468 (ignore mplayer specific stuff, of course) and then either get xkbd working or else edit /home/user/.xmms/config and change device=default to device=bluetooth (in the ALSA section, should be toward the top). It will get really skippy after about 5 seconds. top only reports an average of 40% CPU usage during this though, so it probably isn't CPU related... Also, I did try using both mad and mpg123, there does not appear to be a difference on my n800.

Note: xmms seems really twitchy about config changes, and it likes to change them back. You may have to experiment with changing the config several times before it will accept the changes (it keeps swapping the old values back). This happens to me even when xmms isn't running and I change the config. :/

As far as feedback not related to a2dp: it seems to work very well, the only problem I see at the moment is lack of hildonization... If not for that (and the a2dp issues), I would consider using xmms instead of Kagu/mplayer. Regardless, you are doing a great job, so keep it up!

I have clean working a2dp. In the same screen where you set the alsa device to bluetooth also set "use software control" I also disabled normal mp3 libs only using mad. *Wii*. Not yet 100% but ...closer. Without the click I mentioned the sound was crap mono. Now to play with buffers

I played with the buffers. One thing I found is that smaller is much better than larger. So I did these settings, (on the advanced tab). Seems that larger settings cause too much in the way of drops.

Soundcard
Buffer Time 200ms (minimum)
Period Time 50ms (medium)

Xmms
Buffer Time 1000ms (minimum)

I just tried those settings, no luck. It actually seems to start skipping sooner with that smaller buffersize.

This is the console output from xmms on my system:
Code:
Message: device: bluetooth

I don't know if that is normal... Should it be finding a mixer device? :/

xmms is the best mp3 player on the tablet so far. The gaps inbetween the tracks is the smallest compared to the rest. canola 2 being the worse.

Any chance on the crossfader plugin? Wonder if this would make totally gapless playback?

Why not. I'm building it right now.
I have a new visual plugin (jess), removed goom. I'll update the repo when I get a bit more time.

edit:
It's built but needs a bit of gtk redesigning, window too big. Not a lot too big but enough to not reach the OK/Cancel button

djashjones states above: QUOTE: xmms is the best mp3 player on the tablet so far. The gaps inbetween the tracks is the smallest compared to the rest. canola 2 being the worse. Any chance on the crossfader plugin? Wonder if this would make totally gapless playback? UNQUOTE

I very much endorse this request of djashjones. As I've pointed out elsewhere in this forum, much classical music on CD contains multiple access points which are meant to be played straight through on the cd player. Pauses at these points in the various N800 players I find are very disconcerting and disruptive to the listening and enjoyment of this music. I do not think it is endemic to all mp3 players -- possibly only to the N800. I don't know. My Dell Digital Jukebox effectively plays this type music straight through.
