Summary:                    Speaker test hangs
Description: 
After applying the patch to the library that took out the check for a
proper "start_threshold" (file .../alsa-lib/src/pcm/pcm.c around lines 834
or so), I attempted to try a speaker test again.  It hung right after
outputting "0 - Front Left".  I did an strace and the results are included
in the file attached.  I attempted to vary the sample rate (to 44.1 kHz)
with little luck.  The wierd thing is that I can execute 'aplay' (with the
default device) and get a '.wav' file to play nicely.  I can even get a
multi-channel (4 to be exact) ".wav" file to go thru 'aplay'.  Why
speaker-test doesn't work is beyond me.  The problem is that I appear to
use similar techniques in my own programming as speaker-test, and my
program doesen't do that well.  Being as how speaker-test IS part of ALSA,
I thought I would submit the bug report against it.

If other tests need be preformed, I'd be VERY happy to do them.

It seems that the problem is only on the Revolution 7.1 card, since it
hangs, and the motherboard audio (Via 8235) can generate the audio. 
Results of the tests:
<<<Revo 7.1 card test (card #0)>>>
[tsw ~]$ speaker-test -c2 -Dplug:front:0

speaker-test 0.0.8

Playback device is plug:front:0
Stream parameters are 48000Hz, S16_LE, 2 channels
Using 16 octaves of pink noise
Rate set to 48000Hz (requested 48000Hz)
Buffer size range from 16 to 32768
Period size range from 8 to 16384
Periods = 4

To choose buffer_size = 15052
To choose period_size = 3763
was set period_size = 3764
was set buffer_size = 15052
 0 - Front Left
<<<Hangs, aborted by interupt>>>

<<<Test using the Motherboard audio, card #1>>>
[tsw ~]$ speaker-test -c2 -Dplug:front:1

speaker-test 0.0.8

 0 - Front Left
 1 - Front Right

<<<Audio cycles as intended>>>

Maybe it is the interaction between the Revo 7.1 driver and the speaker
test.  Any more test to be run??

Now that I see the problem only happens on the Revo 7.1 card, do we
transfer it to that driver?  There are the attempts at trying speaker
test:
[tsw ~]$ speaker-test -c 2 -D plug:front:0  <<Attempting to use Revo 7.1
card>>

speaker-test 0.0.8

Playback device is plug:front:0
Stream parameters are 48000Hz, S16_LE, 2 channels
Using 16 octaves of pink noise
Rate set to 48000Hz (requested 48000Hz)
Buffer size range from 16 to 32768
Period size range from 8 to 16384
Periods = 4
Buffer time size 2525
To choose buffer_size = 15052
To choose period_size = 3763
was set period_size = 3764
was set buffer_size = 15052
 0 - Front Left
<interupt after waiting for sound to appear. No such luck!>


[tsw ~]$ speaker-test -c 2 -D plug:front:1   <<Using working motherboard
audio>>

speaker-test 0.0.8

Playback device is plug:front:1
Stream parameters are 48000Hz, S16_LE, 2 channels
Using 16 octaves of pink noise
Rate set to 48000Hz (requested 48000Hz)
Buffer size range from 16 to 16384
Period size range from 8 to 8192
Periods = 4
Buffer time size 2525
To choose buffer_size = 15052
To choose period_size = 3763
was set period_size = 3763
was set buffer_size = 15052
 0 - Front Left
 1 - Front Right
Time per period = 5.649939
 0 - Front Left
<interupted after success at generating white noise.  Works OK>

For reference:

[tsw ~]$ more /proc/asound/cards
0 [Revolution71   ]: ICE1724 - M Audio Revolution-7.1
                     M Audio Revolution-7.1 at 0xdc00, irq 10
1 [V8235          ]: VIA8233 - VIA 8235
                     VIA 8235 with VT1616i at 0xd400, irq 5

Obviously there is a problem in the Revolution-7.1 software.  Is there any
hope?
Has the Revo 7.1 driver changed from version 1.0.9b to the present??

I'd like to get the Revo driver functional, as I've got a project that
uses it
(all 8 channels it really should be called a Revo 8.0!).
