I can't confirm about espeak, or about skype as in bug #361615, but i affected
by this bug in my own apps using Portaudio lib. The same error flood and 20
secs delay arrives even with this simplest test program:
[code]
#include <stdio.h>
#include <stdlib.h>
#include <portaudio.h>
PaStream *stream;
int main(void) {
Pa_Initialize();
Pa_OpenDefaultStream(&stream, 2, 0, paFloat32, 192000,
paFramesPerBufferUnspecified, NULL, NULL);
puts("Finally I started.\n");
return EXIT_SUCCESS;
}
[/code]
and it is noticeable it still not fixed since 2009. On other machine i do not
have bluetooth, and error flood is same, but no start delay. After delay,
applications works correctly. Thanks.

$
"A" way (not ideal! ;-) to resolve the problem is to simply remove the
bluez-alsa package:
$ sudo apt-get remove blue-alsa
Notes:
- I have no bluetooth audio devices within range or enabled.
- I have no ~/.asoundrc so unclear why I'm getting all the alsa cruft.
Attached is the output of 'sudo hcidump -XYt'.
