Summary:                    can't test audio with aplay using 16-bit signed LE
format; 1.0.7 however works
Description: 
I usually test my speakers with aplay using

aplay -t raw -f S16_LE -c 6 -r 48000 -Dsurround51

With 1.0.8, when I do this, nothing goes to any of the speakers. However,
when I revert to alsa-driver 1.0.7, it works correctly. I have Intel ICH5
audio with Realtek ALC650F chip with 5.1 channel audio.

Thanks,
            Uday.

Okay, I now have 1.0.9rc2 versions of both alsa-driver and alsa-lib. I
found that the custom output devices in my .asoundrc are what that are
giving strange noises with 1.0.9rc2 but not with older versions. Here is
my .asoundrc:

pcm.intel8x0 {
    type hw
    card 0
}

ctl.intel8x0 {
    type hw
    card 0
}

pcm.ch51dup {
         slave.pcm surround51
         slave.channels 6
         type route
         ttable.0.0 1
         ttable.1.1 1
         ttable.0.2 0.5
         ttable.1.2 0.5
         ttable.0.3 0.5
         ttable.1.3 0.5
         ttable.0.4 1
         ttable.1.5 1
}

pcm.ch40dup {
         type route
         slave.pcm surround41
         slave.channels 4
         ttable.0.0 1
         ttable.1.1 1
         ttable.0.2 0.5
         ttable.1.2 0.5
         ttable.0.3 1
         ttable.1.4 1
}

Both ch51dup and surround51 give strange noises with xmms; however, when I
changed my output device to "hw:0,0", I get correct output on the two
channels. I have uploaded /etc/asound.state and
/proc/asound/card0/codec97#0/ac97* files (all three concatenated) after I
had set to surround51 and when I was getting that strange noise. 

Also when I tested with speaker-test the following way:

speaker-test -D surround51 -c 6 -s <number>

I found that Rear Left and Rear Right were interchanged with Center and
LFE respectively i.e. for 5 and 6, output was on rear left and right, but
speaker-test was showing them as center and lfe respectively. I am using
1.0.9rc2 version of alsa-utils too.

I would like to add that surround51 is working correctly but not ch51dup
and ch41dup (which I had set up using the route plug-in in .asoundrc).
