Hi folks, I am trying to get btusb to work with my two SCO headsets (BT250 and BT500v) on two different machines (i386 and amd64), both running 2.6.26. I am pretty much following the instructions at http://wiki.bluez.org/wiki/HOWTO/AudioDevices, which are "valid for bluez-utils-3.16 or newer". I am using Debian's 3.36-1 on both machines. My .asoundrc has this content: pcm.bt250 { type bluetooth device "00:07:A4:01:AB:A3" profile "sco" } ctl.bt250 { type bluetooth } and I put the headset into pairing mode, then ran this command: $ strace -f -o /tmp/arecord.strace arecord -f S16_LE -D bt250 >/tmp/test.wav Recording WAVE 'stdin' : Signed 16 bit Little Endian, Rate 8000 Hz, Mono This caused bluetooth-applet to prompt me for the passkey and finally to tell me that the bonding had been established, just as there's a little tone in the headset to acknowledge the connection. However, /tmp/test.wav won't grow, and after a few seconds, arecord exits with $?=0 (!!) after spouting to the terminal: ALSA lib pcm_bluetooth.c:464:(bluetooth_hsp_hw_params) BT_SETCONFIGURATION failed : Input/output error(5) arecord: set_params:979: Unable to install hw params: ACCESS: RW_INTERLEAVED FORMAT: S16_LE SUBFORMAT: STD SAMPLE_BITS: 16 FRAME_BITS: 16 CHANNELS: 1 RATE: 8000 PERIOD_TIME: 125000 PERIOD_SIZE: 1000 PERIOD_BYTES: 2000 PERIODS: 4 BUFFER_TIME: 500000 BUFFER_SIZE: 4000 BUFFER_BYTES: 8000 TICK_TIME: [0 0] /tmp/test.wav is size 0. :( I see precisely the same behaviour with any combination of the two machines, the two headsets and three bluetooth dongles. Yes, I tried them all. Yes, I am somewhat desperate by now. I have bluez-audio installed, but /etc/bluetooth/audio.conf is default. No PulseAudio or anything other than plain ALSA here... Any clues what could be going on? -- martin | http://madduck.net/ | http://two.sentenc.es/ "i wish i hadn't slept all day, it's really lowered my productivity" -- robert mcqueen spamtraps: madduck.bogus@xxxxxxxxxxx
