Summary:                    Aureon 7.1 Universe speakers in incorrect order when
doing a speaker-test
Description: 
I use my Aureon 7.1 Universe with a TerraTec HomeAreon TXR 884 7.1 speaker
set.

I've connected the outputs of the soundard to those of the subwoofer
which
itself connects the small speakers the following way:

Soundcard -------------- Subwoofer --- Small Speakers
Out Front <---------+--> In FL <-----> Front Left Speaker
                    \--> In FR <-----> Font Right Speaker
Out Rear <----------+--> In SL <-----> Side Left Speaker
                    \--> In SR <-----> Side Right Speaker
Out Center/Subwoofer <-> In C <------> Center Speaker
                      \> In Subwoofer
Out Back Surround <----> In BL <-----> Back Left Speaker
                    \--> In BR <-----> Back Right Speaker

You might have a look at soundcard manual page 8
(http://supportuk.terratec.net/modules.php?op=modload&name=Downloads&file=index&req=getit&lid=574)
and speaker manual page 12
(http://supportuk.terratec.net/modules.php?op=modload&name=Downloads&file=index&req=getit&lid=724)
My speakers are placed in my room in a configuration as the 7.1 shown on
page 12
in the speaker manual.

As you note the connection from rear to side is a little bit strange (at
least I
thought so,...) but this seems to be correct, because when I use the
windows
mixer supplied by TerraTec itself, there is a surround test included which
shows
the position of the 8 speakers and let me put the indiviually on and off
and
this leads always to the correct position.

The problem now: I tried the same as under Windows unter Linux with the
speaker-test tool.
I called it via speaker-test -t wav -c 8 and the following came out:
What wav file was played ----- in which speaker position the wav file was
played
"Front Left" ----------------- Front Left Speaker  (correct)
"Front Center" --------------- Center Speaker      (correct)
"Front Right" ---------------- Front Right Speaker (correct)
"Side Right" ----------------- Back Right Speaker  (probably wrong!)
"Rear Right" ----------------- Side Right Speaker  (probably wrong!)
"Rear Left" ------------------ Side Left Speaker  (probably wrong!)
"Side Left" ------------------ Back Left Speaker  (probably wrong!)
"LFE" ------------------------ Subwoofer (correct)

No one could think that I should just switch the speaker cables but that
can't
be a proper solution (not only because this would break settings in the
original
Windows driver (which I only use for Upgrading my Plextor drive firmware
;) ).
I think the configuration of the surround for the Aureon 7.1 Universe has
here
some mistake, hasn't it?

>>If the channels are swapped randomly when running speaker-test , this may
related to https://bugtrack.alsa-project.org/alsa-bug/view.php?id=2026
>Channels are _not_ swapped randomly,.. they are always exactly swapped
like I direct to describe via some ASCII art in the initial bugreport.


speaker-test -c 4 -t wav

In my case (device hw:0,0 support 1, 2, 4 channels) , the four channels
are correct for about 10-20 rounds and the channels are randomly correct
afterwards. 

I expect alsa application use the same buffer size in snd_pcm_writei
except the last write.

I don't expect speaker-test split the last few buffers into small
fragments which some of them are less than the period_size.

I have a fix in https://bugtrack.alsa-project.org/alsa-bug/view.php?id=2023#9452
which seem to eliminate the swap by
speaker-test on my sound card

It's only speaker-test has this behaviour and there is no problem for
aplay and mplayer to play 4-channels pcm wav files.

Ok,.. so I'm going to revert my subdevice change,.. ok? And then (btw: did
you commit that fix you told about already to the hgrepos?) I'll run
speaker-test longer time and see if it does the same...
Anything else I should do?
