First post here, not a developer, but I'm posting here as advised on the bluetooth-alsa site. I have a 3Com 3CREB96 USB dongle and a SonyEricsson HBH-602 headset. I have the following installed on the laptop: kernel 2.6.15 bluez-libs 2.25 bluez-utils 2.25 bluez-hcidump 1.29 btsco 0.41 Bluetooth daemons are running, snd-bt-sco is loaded, hci0 is up, with the voice 0x0060 setting. The devices are paired successfully. I now run btsco -v A1:B2:C3:D4:E5:F6, and get the following response: btsco v0.41 Device is 1:0 Voice setting: 0x0060 RFCOMM channel 1 connected recieved AT*ECBP=? recieved AT+CLIP=1 recieved AT+CSCS="UTF-8" recieved AT+CLAN? In another terminal, I try aplay -B 1000000 -D plughw:Headset test.wav, and the following is added in the btsco terminal: i/o needed: connecting sco... Can't connect SCO audio channel : Connection refused I shut down btsco, and after nearly 30 seconds, I hear a single beep in the headset. I run btsco again as above, with the same initial response, and run aplay again. This time, the sound file plays through the headset, and btsco shows the following: i/o needed: connecting sco... connected SCO channel Done setting sco fd recieved AT+VGS=12 Sending up speaker change 12 speaker volume: 12 mic volume: 11 driver is not in use disconnected SCO channel RFCOMM channel lost btsco then shuts itself down. All the above is consistently reproducable. Also, the same responses are seen if arecord is used instead of aplay, except of course that a file is recorded instead of played on the second attempt. About a year ago, I had the same headset working correctly with btsco and a 3Com BT PCMCIA card, which I unfortunately can no longer use. If more info is required - hcidump, logs, etc - let me know. I am aware that this is a dev list, so I will understand completely if nobody is interested. All the best Tom K. ------------------------------------------------------- This SF.Net email is sponsored by xPML, a groundbreaking scripting language that extends applications into web and mobile media.
