Thanks!*** I just got a generic ISSC dongle and I am trying to get it working with a Jabra BT250 headset, using snd-bt-sco. So far, I can tell I can hear *part* of any wave file I send to the headset. It never completes the entire audio file, though (i.e. aplay hangs forever). I tried using both headset and hands-free profiles (channels 1 & 2 respectively). Both give the same results on the played audio file. Also, it won't work all the times I try. On a lucky day, I was able to send the wave file to the headset for 3 or 4 times in a row. I am still trying to find a pattern in this. All my tests were done using only aplay, as I never got anything using xmms or any other. I will try to provide as much information as possible, but I am new to this bluetooth stuff. I tried searching the archives but couldn't find anything very useful apart from testing with a well-known working dongle, which is not possible for me. Here's some information as requested on the bluetooth-alsa page (btw I use Gentoo): # uname -a Linux gustavo 2.6.11-nitro2 #1 Wed Mar 23 18:28:43 BRT 2005 i686 mobile AMD Athlon(tm) XP2400+ AuthenticAMD GNU/Linux # epm -qa |grep bluez bluez-libs-2.15 bluez-hcidump-1.18 bluez-utils-2.15 # hciconfig -a hci0: Type: USB BD Address: 00:11:67:02:D7:34 ACL MTU: 678:8 SCO MTU: 48:5 UP RUNNING PSCAN ISCAN RX bytes:440 acl:0 sco:0 events:21 errors:0 TX bytes:324 acl:0 sco:0 commands:21 errors:0 Features: 0xff 0xff 0x0d 0x00 0x00 0x00 0x00 0x00 Packet type: DM1 DM3 DM5 DH1 DH3 DH5 HV1 HV2 HV3 Link policy: RSWITCH HOLD SNIFF PARK Link mode: SLAVE ACCEPT Name: 'Pavilion' Class: 0x3e0100 Service Classes: Networking, Rendering, Capturing Device Class: Computer, Uncategorized HCI Ver: 1.1 (0x1) HCI Rev: 0x1a4 LMP Ver: 1.1 (0x1) LMP Subver: 0x1a4 Manufacturer: Integrated System Solution Corp.
