Mixed Results Playing mp3

Mixed Results Playing mp3

[John Frankish]

I've been trying various tools to play mp3 files to a Bluetooth headset whilst I decide whether to buy some a2dp headphones . Using the following and the .asoundrc at the bottom of the post:

bluez-4.41
dbus-1.2.14
dbus-glib-0.80
alsa-1.0.20
kernel-2.6.29.2

I get the following results:

1. mplayer-gtk1 (svn 29308): plays without problems

2. xmms-1.2.11: no error messages, but produces "noise" and "clicks" (the bluez wiki mentions "issues" with xmms).

3. aplay-1.0.20: Is it possible to play mp3 with aplay, if so, what command is required?

4. mpg123-1.8.1: "mpg123 -v -a plug:bluetooth file.mp3", "mpg123 -v -a bluetooth file.mp3", no error messages, but produces "noise" and "clicks"

I don't see why xmms and mpg123 wouldn't work and there are no error messages or pointers from "bluetoothd -dn" - does anybody have any ideas?

-----------
pcm.rawbluetooth {
   type bluetooth
   device 00:12:EE:A6:1D:F4
}

pcm.bluetooth {
   type plug
   slave {
      pcm {
         type bluetooth
         device 00:12:EE:A6:1D:F4
      }
   }
}

aplay will not play mp3 encoded files.

Please refer to here:

http://wiki.bluez.org/wiki/HOWTO/AudioDevices

Your asoundrc differs from the example.

Does your mpg123 support alsa?

Your asoundrc differs from the example.

Does your mpg123 support alsa?

Whether .wav file play through 'aplay' is working fine for you?

At my side, I can hear only a beep tone. Please find the "bluetoothd 
-nd" log:

*Which is the SCORouting we need to give on the audio.conf, by default 
it is HCI?*


I do not have X server on my linux box, please suggest which are all the 
command line audio players I can use.

Please advice.
Thanks & Regards,
Benjamin

Yes, I didn't mention it, but aplay is working fine with a wav file

It could be that mpg123 is using OSS and not ALSA directly.  Make sure 
ALSA is being used.

This could also be totally unrelated.

Any ideas about this? I'm using the latest versions of bluez, dbus, alsa, mpg123, etc- there must be some reason why mplayer will play mp3 over Bluetooth and mpg123 will not.

Are there any tests I can run to try and narrow down the problem?

Thanks, John
