Hmm, are you using CVS version of alsa-lib or 1.0.8?
The config file I sent was for CVS version.

The message was created with alsa-lib-1.0.8 on RedHat 7.3 (kernel 2.4.26)
Now I switch to CVS on FC3. I found the result is opposite:

alsa-lib-1.0.8+RH 7.3, front, rear can be used as -D option, while default shows the above message.

alsa-lib CVS+FC3 it is ok to "aplay" directly or "aplay -D default", but either front or rear I got
ALSA lib pcm.c:1939:(snd_pcm_open_conf) Cannot open shared library /usr/lib/alsa-lib/libasound_module_pcm_softvol.so
aplay: main:508: audio open error: No such file or directory

The libasound.so.2.0.0 is installed successfully and there is no /usr/lib/alsa-lib path
in my system (should I create?) Please help!

Sincerely,
ChenLi Tien

Finally I got a clue.
The FC3 install the alsa-lib (libasound.so.2.0.0) at /lib, while the alsa-cvs and alsa-lib-1.0.8
install it in /usr/lib, no wonder the softvol cannot run with it! Finally I get PCM volume
appear. Thanks for your help and sorry that it took me so long to discover this.

It's weird.
Please make sure that your cvs tree is all updated properly.

/usr/lib/alsa-lib is the extra path for plugin shared objects.  The
plugins alsa-plugins repository are installed there.  However, the
standard plugins are included in libasound.so.  So, you don't need to
create this directory at all.

Just to be sure: your system is i386, not AMD64, right?

I use alsa-driver and alsa-lib from cvs but alsa-util  from 1.0.8 because I have problem
conigure the alsa-util tree.

My system is an i386 system (P4).

It is turned off, indeed.  In the configuration:

			{
				name "Four Channel Mode"
				lock true
				preserve true
==>				value false
			}

Then I think following lines should be added too:

CMI8738-MC8.pcm.surround41.0 "cards.CMI8738-MC8.pcm.surround40.0"

CMI8738-MC8.pcm.surround50.0 "cards.CMI8738-MC8.pcm.surround40.0"

Both are OK.  Thanks.

The softvol won't create a control if it already exists in h/w, and
skips the software attenuation.  But, in your patch, PCM Playback
Volume control is removed, so it should work...

Did you try my config file I sent you in the last mail?

Should it be instide the patch or just like:

I still cannot use the softvol with 8768, but softvol works with the 8739 so I don't
know if anything need to do except not setting PCM Playback Volume item for mixer.

Thanks for the patch.  It looks fine.

Could you provide a "Signed-off-by" line to keep your credit in
changelog, such as

	Signed-off-by: Foo Bar <foo@bar.com>

This is required to submit to linux-kernel.


thanks,

Takashi

[-- Attachment #1: Type: text/plain, Size: 462 bytes --]

Hi,

I made a patch for CM8768, which has the same PCI ID but there are
several HW diffecece, aas listed:

1. 8768 has no PCM volume control.
2. The ADC of 8768 can only record in 44.1kHz or 48kHz.
3. 8768 can support up to 8 channels.

I made change for item 2 and 3, I want to use the softvol plugin but
don't know how to. The driver just don't generate the PCM volume slider
 for now.

The patch file is attached.

Sincerely,
ChenLi Tien
