GOAL: skype/SIP conversation while listening to music stream that's
merged into conversation. Hoping to find changes needed to .asoundrc
below.
Below my 'aplay -l' here I have posted an .asoundrc I found that seems
to just need something added or changed so that an mplayer/aplay
stream can be played into the headset mic inputs.
Usually I have some problem with aplay/mplayer when I try to play into
the various .asoundrc points. The .asoundrc below is fine with
mplayer/aplay though it's written for multiple output and not multiple
input. I think?
And of course I don't actually hear anything when I send audio to the
aloop parts. ie. pcm.p_card1in0 AND pcm.p_card1out0.
mplayer doesn't stop with an error though, which is good. So now, how
to get music into a skype/sip conversation so it can be heard by both
people in a conversation while talking?
Hoping an alsa guru might respond. I'm hoping that there must be
someone here that can tell me.
Not had success at all yet.
Really really struggling to create an .asoundrc that will allow:
Having a conversation via skype/SIP with both parties listening to an
mplayer/aplay generated music track merged into the outgoing
microphone (headset) channel.
I've been reading alsa docs for weeks and have tried dozens of various
.asoundrc and edits of. Tried pulse audio with alsa, jack with alsa,
etc. etc. etc.
Currently dedicated to finding a way to do this with ALSA only (not
jack/pulse at this time) I have done a fresh 'alsa only' install which
has helped. AND: I have managed to get a working aloop driver
installed as my aplay -l below shows.
I'm at the point of not know at all what to try next. It appears that
by using alsa aloop/dsnoop/asym/multi plugins (which I've tried and
tried with) I should be able to dsnoop/aloop/multi a command line
mplayer or aplay stream INTO the voip chat. Many of the .asoundrc I've
tried would allow the music track to be played (mplayer/aplayer cli)
and also allow a voip conversation as well. Just can't get the music
into the stream of the conversation.
The most immediate way, I've thought should be to have the music track
playing into card0 (the internal hda-intel chip), then loopback that
into the input of the cmedia usb headset. Thereby allowing the
conversation to occur while the music is played clearly as the
mplayer/aplay stream is not fighting for the soundcard. help?!
I have tried dmix and so much else. I need to have the music looped
back into the mic input channels, don't I?
Can anyone tell me what I've missed. I won't post the many many many
things I've tried though happily could post some of the .asoundrc
segments as a response should anyone have any ideas. Here's one below
that's great though backward perhaps.
I've probably read/tried most of the code found on all the alsa lists.
Absolutely stumped at this point as i don't yet have the understanding of what
needs to happen.
thanks!!!!!

BELOW : .asoundrc I found that works with aloop though it's sorta the
opposite in that it records and I need to play a stream IN. Though the
aloop parts does allow mplayer/aplay stream to be sent to them. What
would I add or change to get music INTO the voip/skype conversation
microphone channels?
