What's the difference between using > pcm_a2dpd2 and the "alsa redirect"? I didn't catch what "same as the > headphones" was referring to either. In retrospect I think I wasn't clear about pcm_a2dpd and pcm_a2dpd2. By those I meant the alsa plugins (libasound_module_pcm_a2dpd[2].so) as opposed to the similarly named daemon and NOT a definition in my .asoundrc. The "alsa redirect" meant setting enableredirectalsa=1 in .a2dprc. I gather that this causes the a2dpd system to spit sound back out through alsa to speakers instead of through a bluetooth connection. To restate more clearly (maybe) I'll give you a chart: a2dpd plugin ("type a2dpd" in .asoundrc): bluetooth headphones (enableredirect=0 in .a2dprc): occasional chirps almost no traffic through hcidump flags=1 only gives info upon occurrance of chirps normal computer speakers (enableredirect=1): music sounds fine a2dpd2 plugin ("type a2dpd2"): bluetooth headphones (enableredirect=0): garbled, sped up sound plenty of hcidump traffic flags=1 reports once a second or so normal computer speakers (enableredirect=1): garbled, sped up sound ring buffer full messages spew forth An interesting thing to me is that enableredirect, if it does what I think it does, seems to show a non-bluetooth problem... ~Chris ------------------------------------------------------------------------- This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML.
