can somebody show me an example asound configuration for dmixing with hifi bluetooth speakers/headset

[Jelle de Jong]

[-- Attachment #1: Type: text/plain, Size: 728 bytes --]

Hello everybody,

I have been periodically trying to get multiple audio sources to play
together (dmixing) to a hifi bluetooth speaker system or hifi bluetooth
headset.

I am using only alsa and no pulseaudio, esd, jack, mas of something else
just alsa with asoundrc configuration files and no graphical environment.

Can somebody show me an example asoundrc config file to make it possible
to use software audio mixing with my bluetooth devices. If this is
currently not possible, please tell why and what we can do about it. I
am willing to donate some payal money to the person providing me with a
working asoundrc configuration file that allows me to play multiple
audio sources at the same time.

Thanks in advance,

Jelle

Bump for the mail, I still have this issue, and would really appreciate
somebody taking a look at. I don't know if there is code limitation or
that it is just a asoundrc configuration issue.

Please help,

Best regards,

Thank you for responding, I had reattached the configurations and
outputs with some more info. I have already spent a bloody awful lot of
time on testing with trial and error. I am not an alsa or bluetooth
developer I cannot get it to work. If a capable person could get it
working I would be very great full.

I am also not able to get bluetooth working without adding a sound card
to my system, so i put in a usb sound dongle just to get bluetooth with
alsa working, alsa won't load its modules without it first finding a
soundcard. It is all very very confusing.

Thanks in advance for any help,

Best regards,

Jelle

Hello Jelle,

I will setup the environment and do some tries as well. I'll come back
to you when some outcome will be available

Hello Jelle,

You need to setup a passkey agent (for bluez 3.x) for connection to
succeed. I've attached one simple

For dmix setups you have to define slaves as "pcm_slave." not "pcm."
is .asoundrc

Hope this helps.

Thank you Leonid for responding. I gave it a good try again, with trial
and error with all kind of variations of the different asoundrc files I
attached in my previous mails. I am unable to get it working with two
audio streams to one bluetooth devices (mixing).

I ended up with lots of messages like "Unknown field pcm_slave". Could
you please post a complete asoundrc file that has been tested to work
with two speaker-test -c2 programs running beside each other?

Just to be clear, I have no problem getting my bluetooth audio device to
work with single audio streams, I would like to have mixing support
working so I can play multiple audio sources at the same time.

Thanks in advance,

Jelle

Hi Jelle,

I've digged there a bit and found out the following:
1. you cannot use dmix over bluetooth as bluetooth is implemented as a
plugin but dmix works with cards only
2. bluetooth itself doesn't do mixing

so dmix is not a thing which could help you here, but...
I have one crazy idea for you :)
you can try to setup alsa jACK plugin and then setup jACK to use your
alsa bluetooth device. Thus if jACK supports mixing itself (which most
probably the truth) the whole setup should work as you want.
Unfortunately, I don't have jACK installed so cannot give it a try.

Vale,
Leonid Movshovich

Thank you Leonid for confirming my issues getting mixing to work with
alsa and bluetooth.

I don't really like jack or pulseaudio, and would like to stick with
alsa a while more until all the bugs, usability, and performance issues
are gone. I do not feel like going into there issues in this mail,
because the mail would get 4 pages long, please search with google for
"pulseaudio broken" and find some answers.

My real question is, what would it take to fix the alsa plugin to make
it possible to use streaming. Maybe bluetooth devices should work as
cards... this would also solve the problem that I cant use bluetooth
without a dummy usb soundcard insert into my system. Alsa would not
start without finding a soundcard...

Is somebody willing to take a look at the alsa system for bluetooth?
What would resources or rewards would you like to fix it?

Best regards,

Jelle
