Hi All,
I am using ALSA 1.0.24 with the attached asound.conf. I am attempting to
share (mix) the analog output between Asterisk and aplay. However, when
Asterisk is running, my application throws an error when attempting to play
a wave file via aplay. If I stop Asterisk, aplay plays the wave file just
fine. If I remove the asound.conf file, Asterisk and aplay are both happy
and share the analog output just find with the default ALSA dmix
implementation. However, we need this asound.conf to work for us for other
reasons. What is wrong with it. I have even tried replacing dmix with
dshare and get the same bad behavior. We are running CentOS 6.0. As a
caveat, I am attempting to use dmix with analog audio. If I use it with
HDMI audio, it works flawlessly (same asound.conf with tweek to specify
HDMI). Thanks in advance for your help.

;------------------------------ JITTER BUFFER CONFIGURATION --------------------------
; jbenable = yes ; Enables the use of a jitterbuffer on the receiving side of an
; ALSA channel. Defaults to "no". An enabled jitterbuffer will
; be used only if the sending side can create and the receiving
; side can not accept jitter. The ALSA channel can't accept jitter,
; thus an enabled jitterbuffer on the receive ALSA side will always
; be used if the sending side can create jitter.
; jbmaxsize = 200 ; Max length of the jitterbuffer in milliseconds.
; jbresyncthreshold = 1000 ; Jump in the frame timestamps over which the jitterbuffer is
; resynchronized. Useful to improve the quality of the voice, with
; big jumps in/broken timestamps, usually sent from exotic devices
; and programs. Defaults to 1000.
; jbimpl = fixed ; Jitterbuffer implementation, used on the receiving side of a SIP
; channel. Two implementations are currently available - "fixed"
; (with size always equals to jbmax-size) and "adaptive" (with
; variable size, actually the new jb of IAX2). Defaults to fixed.
; jblog = no ; Enables jitterbuffer frame logging. Defaults to "no".

Looks like the open of HD-audio stream failed by some reason.
When you open via aplay, is the corresponding stream already opened
by another? Take a look at /proc/asound/card0/pcm0p/sub0/* files.
Also, try the latest alsa-driver snapshot in
ftp://ftp.suse.com/pub/people/tiwai/snapshot/

Hi Takashi,
Thanks for the quick response. Yes, the HD-audio stream open fails because
Asterisk has previously opened it. aplay cannot open it (error -22).
However, dmix should remedy the situation. It should provide software
mixing for Asterisk and aplay so that the output of both is mixed and output
to the analog audio channel. I will try your latest drivers.
Best Regards,

This same scenario works flawlessly with HDMI channel. Asterisk and aplay
out put is mixed and send to the HDMI channel.

-22 is -EINVAL, and it's not -EBUSY or -EAGAIN. If a blocking open is
the problem, it should have been -EAGAIN or such.
That is, usually something conflicts with the opened stream.
