I have two virtual device pointing to same Alsa card ,with different bindings
When audio played on both device [dmix_4_channels and dmix_2_channels] in
parallel. Audio played on dmix_2_channels is getting corrupted.
Validated with alsa version : 1.2.3
Please let me know how to make it work with

Maybe; this happens if you attenuate 16-bit samples too much.
Is that mixer control implemented in
Hello,
I am running raspbian with alsalib version 1.0.25 and driver version
k3.8.10+. The kernel is compiled according to the instructions here:

wm8731 does not support hardware mixing, I am using the dmix plugin, but I

All programs using a dmix device must share a common period size, so the
dmix plugin chooses one before the first client is opened.
It's possible to configure this value:

Hello All,
I'm curious if the Dmix plugin has a fixed period size and, if so, how
to deal with that. I'm a bit of an ALSA newbie, so please forgive any
confused assumptions in the question. Here's the symptoms I am seeing
and the problem I am trying to get at:

Hi,
It is really still true that you cannot put anything (like a ladspa plugin)
after dmix?
I also asked the question here:
https://bbs.archlinux.org/viewtopic.php?pid=859465#p859465
Scrap about this:

Isn't there a workaround?

I'm setting up ALSA to allow for multiple non root users to
similtanously access audio (meaning I'm using dmix).
I've been doing some reading and it seems I need to do the following.
1) "ipc_perms" to "0666" (or similar to allow non root access)
2) "ipc_key_add_uid" to "false"
3) "chmod" the f

OK. I took my chances and copied and pasted this into an .asoundrc and
with a little tweaking, I got the emi26 to play sound nicely without
the crackles! good.
I would like to get the other 4 ouputs to work as well though. I tried
to just add this to bindings:

hello,
I would like to get my emi26 work with jack (the problem is some
endianess issue witht the card, periodic crackles in the sound, NOT
xruns in this case). The card works perfectly with alsa and oss, but I
need it together with jack for SuperCollider. How would it be possible
to solve this en

is there anyway to set up alsa using the dmix plugin so that multiple
local users can access the sound card? at the moment the first user can
use the soundcard with dmix, but when another user tries they do not
have the required permissions.

My Pentium 200 can do five streams or so without any problems. I never
tested with more, so I
Hi,
What is the lowest speed CPU that anyone has had success with the dmix
plugin on? It seems that even when only playing one stream, if the cpu
is too slow, the sound cuts out.
Also, is there any way to prevent the OSS device from being blocked if
the ALSA is being used? The dmix plugin prev
