(NOTE: RESENT as received an email the alsa-devel mailinglist had moved.)
OBJECTIVE: merge (mplayer cli or aplay) audio stream with SIP/Skype so that music can be heard during chat.
Really need help from a developer I think as alsa-users mailinglist not able to help during past 2 weeks.
2 weeks happily studying alsa/plugins, posted/searched on mailing lists and tried irc as well. Could really use a guru assist. I get the parts mostly, though obviously not how it all comes together in an .asoundrc.
- aloop driver is installed.
After scores of attempts now wondering: maybe having the music track playing on it's own soundcard or loopback and having that merge into the microphone? channel of sip/skype's soundcard.
Like, have the music play out on the intel card 0, and loopback through aloop card 1, then merge that with asym/dmix onto sip/skype's headset card 2 ????
I kinda know what the plugs do, though not how to hook-up through .asoundrc.
I've found 3 or 4 great posts on alsa-devel and alsa-users though ultimately for me just glimmers of working.
Rather than glut up the list here I've only posted my aplay -l Can anyone comment on exactly what I'd put in my .asoundrc? What the flow/parts would be even? To stop stuttering (fighting for card control ? etc.) I guessed that the music playing on it's own card might be good?
Very happy to post what I've got though thought I should ask first if anyone has found a best practice for this.
