Now I'm lost again. Is there an audio transcoding somewhere in the SCO layer, so that I could simply send PCM_S16 and the SCO layer transcodes the audio if the headset does not support this? I mean there must be a reason why the original snd-bt-sco developer hardcoded the 8bit format instead of using 16 bit. What about audio quality during transcoding? MULAW sounds much better than PCM_S8. I have just a hard time with "accept 0x0060 because - ." Sorry that I don't fully understand this bluetooth stuff, I'm trying my best here. :( I hope I dont make anyone angry or something... | | |>As soon as this works again, I'll put a new patch together and make it |>available. | | | What kind of patch? We need dynamic alternate setting adjustment for the | hci_usb driver. Nothing else. sorry, misunderstanding. I'll make a new version of snd-bt-sco that builds with alsa-1.0.5a. Nothing for bluez. I'd like to help you out with this dynamic alternate setting adjustment, but I think I don't know enough usb and/or bluetooth mojo to do anything usefull. To make my headset work for now (need my "phone") I used that bad kernel patch again, but I'll try to do everything to avoid that in the release. I just have to understand what's going on... cu, ~ Lars -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.3 (GNU/Linux) Comment: Using GnuPG with Thunderbird - http://enigmail.mozdev.org iD8DBQFA0N/+QWC6DTWkDAoRArSUAJ4p4tJgUHZNgynBUdmQVyyGLR53lwCdGAe/ KLuMLz+uvuTKLaIO1yB8s9E= =ZqlF -----END PGP SIGNATURE----- ------------------------------------------------------- This SF.Net email is sponsored by The 2004 JavaOne(SM) Conference Learn from the experts at JavaOne(SM), Sun's Worldwide Java Developer Conference, June 28 - July 1 at the Moscone Center in San Francisco, CA REGISTER AND SAVE! http://java.sun.com/javaone/sf Priority Code NWMGYKND _______________________________________________ Bluez-devel mailing list Bluez-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/bluez-devel
