I've got an Arctic P311 bluetooth headset[1] and on my PC, I'm using a Hama Nano-Bluetooth-USB-Adapter Version 3.0+EDR Class1 dongle[2]. The system is a openSUSE 11.4 64bit PC with KDE 4.6.0 and PulseAudio pulseaudio-0.9.22-6.11.1.x86_64. I noticed, that the audio output in a2dp mode is quite "jerky" (haven't tried the mono hsp mode). Not really surprisingly, I found a lot of messages like the following in my /var/log/messages, when I grep for "pulseaudio"[3]: […] Sep 9 11:37:38 ewzw032 pulseaudio[2984]: module-bluetooth-device.c: Skipping 296858 us (= 52364 bytes) in audio stream […] Sound thus sounds terrible. When I then disconnect the Bluetooth connection and connect again, sound is fine. At least most of the time - earlier today, sound was messed up also right after building the connection. Normally, I play music with Amarok. But I found, that even much more simple commands like the following create bad output: paplay -d bluez_sink.00_1A_7D_60_67_1F -p /usr/share/sounds/pop.wav env PULSE_SINK=bluez_sink.00_1A_7D_60_67_1F \ mpg123 -a pulse /home/ask/tmp/Test.mp3 In "lsusb", the BT dongle is this: Bus 001 Device 048: ID 0a12:0001 Cambridge Silicon Radio, Ltd Bluetooth Dongle (HCI mode) You can find the "lsusb -v" output for this device on pastebin[4]. Is there anything that can be done about this?
