This is reported against an old version of Ubuntu and many things has changed since then. Because of that we won't fix this issue however if this behavior repeats on a modern version please fill a bug report against it and we will take it from there.

This christmas I got (myself actually) an Acer Aspire One 110A and installed Ubuntu 8.10, plugged in a tiny bluetooth adapter, installed banshee and rhythmbox, paired up and off I went. It worked great but with a shorter range (failed to keep music playing while going to bathroom :) However, I just recently updated to 9.04 and now playback has started to behave really bad. What happens is that it sounds just like I'm out of range - it gets choppy and after some time it fast forwards (skips frames) to get back in sync. lsusb says: Bus 002 Device 002: ID 0a12:0001 Cambridge Silicon Radio, Ltd Bluetooth Dongle (HCI mode) Looking at /var/log/syslog this is what I get after doing a /etc/init.d/bluetooth restart (I do that whenever I forget to turn playback off when leaving my desk and return after a few minutes): Jul 15 15:41:44 acer bluetoothd[16817]: Bluetooth daemon Jul 15 15:41:44 acer bluetoothd[16817]: Starting SDP server Jul 15 15:41:44 acer bluetoothd[16817]: Starting experimental netlink support Jul 15 15:41:44 acer bluetoothd[16817]: Failed to find Bluetooth netlink family Jul 15 15:41:44 acer bluetoothd[16817]: bridge pan0 created Jul 15 15:41:44 acer bluetoothd[16817]: Registered interface org.bluez.Service on path /org/bluez/16817/any Jul 15 15:41:44 acer bluetoothd[16817]: HCI dev 0 registered Jul 15 15:41:44 acer bluetoothd[16817]: HCI dev 0 up Jul 15 15:41:44 acer bluetoothd[16817]: Starting security manager 0 Jul 15 15:41:44 acer bluetoothd[16817]: Registered interface org.bluez.SerialProxyManager on path /org/bluez/16817/hci0 Jul 15 15:41:44 acer bluetoothd[16817]: Registered interface org.bluez.NetworkPeer on path /org/bluez/16817/hci0 Jul 15 15:41:44 acer bluetoothd[16817]: Registered interface org.bluez.NetworkHub on path /org/bluez/16817/hci0 Jul 15 15:41:44 acer bluetoothd[16817]: Registered interface org.bluez.NetworkRouter on path /org/bluez/16817/hci0 Jul 15 15:41:44 acer bluetoothd[16817]: Registered interface org.bluez.Service on path /org/bluez/16817/hci0 Jul 15 15:41:44 acer bluetoothd[16817]: Registered interface org.bluez.Headset on path /org/bluez/16817/hci0/dev_00_18_13_DB_F4_0C Jul 15 15:41:44 acer bluetoothd[16817]: Registered interface org.bluez.AudioSink on path /org/bluez/16817/hci0/dev_00_18_13_DB_F4_0C Jul 15 15:41:44 acer bluetoothd[16817]: Registered interface org.bluez.Control on path /org/bluez/16817/hci0/dev_00_18_13_DB_F4_0C Jul 15 15:41:44 acer bluetoothd[16817]: Registered interface org.bluez.Serial on path /org/bluez/16817/hci0/dev_00_18_13_DB_F4_0C Jul 15 15:41:44 acer bluetoothd[16817]: Registered interface org.bluez.Input on path /org/bluez/16817/hci0/dev_00_18_13_DB_F4_0C Jul 15 15:41:44 acer bluetoothd[16817]: Adapter /org/bluez/16817/hci0 has been enabled Then, I start playback in banshee, music starts playing (sounds OK) and syslog shows Jul 15 17:31:59 acer bluetoothd[16817]: link_key_request (sba=00:1B:DC:02:0F:7E, dba=00:18:13:DB:F4:0C) Jul 15 17:32:00 acer bluetoothd[16817]: Can't open input device: No such file or directory (2) Jul 15 17:32:00 acer bluetoothd[16817]: AVRCP: failed to init uinput for 00:18:13:DB:F4:0C Just as I write this report and hit play above, I just got 1:17 minutes of OK playback, but then it started chopping and at 1:37 it was back in sync. I'm playing an ogg file that I've listened to (thousands of times - last.fm can confirm this), so there's nothing wrong with the file. My comple .asoundrc: pcm.bluetooth { type bluetooth device 00:18:13:DB:F4:0C # tiny #device 00:1B:DC:02:0F:7E # tiny nr 2 } I've run "vmstat 1" in a console to see if there's something special happening but I can't find any pattern from that. I'm running the standard kernel, all packages updated. My /boot/grub/menu.lst does include # defoptions=enable_mtrr_cleanup mtrr_spare_reg_nr=1 quiet splash which is related to MTRR registries bug(s) in kernel and intel. I've reniced bluetoothd, pulseaudio and banshee to -10 (using htop) - no change. I'm out of ideas on what to try. I'm willing to try most ideas as I'm getting crazy listening to people walk by in the corridor at the office ... ceda@acer:~$ lsb_release -rd Description: Ubuntu 9.04 Release: 9.04 ceda@acer:~$ LANG=C apt-cache policy bluez gnome-bluetooth bluez: Installed: 4.32-0ubuntu4.1 Candidate: 4.32-0ubuntu4.1 Version table: *** 4.32-0ubuntu4.1 0 500 http://se.archive.ubuntu.com jaunty-updates/main Packages 100 /var/lib/dpkg/status 4.32-0ubuntu4 0 500 http://se.archive.ubuntu.com jaunty/main Packages gnome-bluetooth: Installed: 0.11.0-0ubuntu4 Candidate: 0.11.0-0ubuntu4 Version table: *** 0.11.0-0ubuntu4 0 500 http://se.archive.ubuntu.com jaunty/universe Packages 100 /var/lib/dpkg/status ceda@acer:~$ aptitude search bluez i bluez - Bluetooth tools and daemons i bluez-alsa - Bluetooth audio support p bluez-btsco - Bluez Bluetooth SCO tool p bluez-compat - BlueZ 3.x compatibility binaries i bluez-cups - Bluetooth printer driver for CUPS i bluez-gnome - Bluetooth utilities for GNOME i bluez-gstreamer - Bluetooth gstreamer support p bluez-hcidump - Analyses Bluetooth HCI packets p bluez-pcmcia-support - PCMCIA support files for BlueZ 2.0 Blueto i bluez-utils - Transitional package i A python-bluez - Python wrappers around BlueZ for rapid bl v python2.5-bluez - v python2.6-bluez - ceda@acer:~$ aptitude search bluetooth i bluetooth - Bluetooth support i gnome-bluetooth - GNOME Bluetooth tools. i gpe-bluetooth - Bluetooth connectivity tool for GPE p kdebluetooth - KDE Bluetooth Framework p libbluetooth-dev - Development files for using the BlueZ Lin i libbluetooth3 - Library to use the BlueZ Linux Bluetooth v libbluetooth3-dev - p libmultisync-plugin-irmc-blueto - Adds Bluetooth support to the IrMC plugin p libnet-bluetooth-perl - Perl Bluetooth interface v python-bluetooth - To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/bluez/+bug/399803/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
