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.

The mixer configuration is okay. I actually reverted to alsa 1.0.7 (the
driver) and then tried, and it worked perfectly. aplay gives the usual
noise. Also, with alsa 1.0.8, I can play music with xmms or any other
player correctly but the rear right channel stops working after some time.
Output to all other channels works fine. I also confirmed this with
speaker-test.

I tried 1.0.9rc2. After installing 1.0.9rc2 versions of the driver and
lib, when I tried to play music (with xmms), some kind of strange repeated
noise comes out of the speakers instead of the music. The culprit seems to
be alsa-lib 1.0.9rc2; when I reverted to alsa-lib 1.0.8 with 1.0.9rc2
driver and utils, it worked correctly; but still aplay doesn't send output
on S16_LE in any of these cases except when I have alsa-driver-1.0.7.

OK, then could you attach /etc/asound.state and
/proc/asound/card0/codec97#0/ac97* files on 1.0.9rc2 for debugging?

For testing, use speaker-test to eliminate unknown factors.

Rear-right channel problem was fixed recently.  It should be OK on
1.0.9rc2.

The noise on 1.0.9rc2 looks strange.  It might be due to dmix plugin, but
still this doesn't explain what really happens there.  Anyway, always use
the same ALSA driver version with the alsa-lib.
