[Dave <1242272@xxxxxxxxxxxxxxxxxx>]

I can supply additional logs/traces. After 13.04 -> 13.10 upgrade,
Ubuntu rendered my BT speakers useless. I'm on -generic amd64 kernel
with 16GB RAM and a quad-core CPU (top of the line Lenovo T530
notebook).

I had to delete+re-pair via blueman, then it started working, but I've
been getting constant audio freezes/stutter ever since. This is the
reason, although why it happens I have no idea - no other messages
anywhere, CPU is idling, memory in abundance:

Dec  4 19:18:24 ce02817 pulseaudio[3184]: [bluetooth] module-bluetooth-device.c: Skipping 40407 us (= 7124 bytes) in audio stream
Dec  4 19:18:24 ce02817 pulseaudio[3184]: [bluetooth] module-bluetooth-device.c: Skipping 41043 us (= 7236 bytes) in audio stream

The "stutters" are actually rather long audio dropouts (up to 1.5sec,
definitely not in us range), usually in a sequence of 2-5 then about a
minute OK and repeat. Before the upgrade, none BT/audio issues
whatsoever (same speakers).

Additionally, all audio (even the speaker check in control centre) is
delayed by about 2-3sec when routed via BT. As in: click "Left speaker",
button depresses, nothing for 2-3sec, then sound. Clicking left, right,
left: the same, all played like a delayed FIFO.

Possibly related is another problem - in Pulse Audio. After
suspend/resume while listening to BT, system audio is dead and cannot be
restarted. Mplayer output gives:

  CPLAYER: ==========================================================================

 AUDIOOUT: [AO_ALSA] Playback open error: Device or resource busy
 AUDIOOUT: Failed to initialize audio driver 'alsa'
  CPLAYER: Could not open/initialize audio device -> no sound.
  CPLAYER: Audio: no sound

The reason is that:

Dec  4 20:13:41 ce02817 pulseaudio[7221]: [autospawn] core-util.c: Failed to create secure directory (/run/user/1000/pulse): Permission denied
Dec  4 20:13:41 ce02817 pulseaudio[7221]: [autospawn] lock-autospawn.c: Cannot access autospawn lock.
Dec  4 20:13:41 ce02817 pulseaudio[7221]: [pulseaudio] main.c: Failed to acquire autospawn lock
Dec  4 20:13:41 ce02817 pulseaudio[7223]: [autospawn] core-util.c: Failed to create secure directory (/run/user/1000/pulse): Permission denied

Dec  4 20:13:41 ce02817 pulseaudio[7223]: [pulseaudio] main.c: Failed to acquire autospawn lock

because /run/user/1000/pulse is suddenly owned by root. The PID stored
in /run/user/1000/pulse/pid does exist, but it's not a root nor setuid
root process:

dave      3184     1  0 pro01 ?        00:14:49 /usr/bin/pulseaudio
--start --log-target=syslog

The words "WTF" come to mind. I literally haven't had so many things
broken with my desktop since upgrading good old Debian to Potato back in
~2001, but stable release Saucy trumps even that, because I can't even
login to the desktop environment (after logging in, all sessions hang
around gnome-keyring-daemon step with blank unkillable desktop). None of
them! Not Flashback, not even my own (freedesktop compliant!) cusom WM
gnome-fluxbox .session that worked for ages (and no, I have no desire to
click & fight my way through that pathetic excuse for Linux Desktop
Environment called Unity, so I haven't tried that one).

Don't get me wrong, I did enjoy my funky Ubuntu ride through Maverick -
Natty - Oneiric - Precise - Quantal - Raring, but it's time to return
home. This "We're doing it our way, because it's The Best Way, so screw
the rest" attitude adopted by most distros in the early days of Linux
was precisely why I've fallen in love with the unassuming and open
philosophy of Debian back in 90s. If Ubuntu's mission is to entice noobs
while alienating gurus and power users, well, then congrats to a job...
done.
