Hello,
First of all, since this is my first message I hope am not mistaken
reporting this two issues about this piece of hardware (I was pointed here
by alsa irc support channel) and bug tracker url does not seem to work, so
I decided to post it here.
Problem: Errors with mixer controls, breaking alsamixer, and not working
7.1 support.
Scenario: Siberia Elite Prism soundcard supports 7.1 channels but it seems
it can only play FRONT LEFT and FRONT RIGHT channels, no matter the setup.
Here is the alsa-info script output:
http://www.alsa-project.org/db/?f=301e6045129665d086d2571652c62648de0eac99

Also in syslog I often can see messages related to this device:

usb 1-1.3: 2:1: cannot get freq at ep 0x1
Loading alsamixer and trying to select the soundcard exits the program with
this message:
cannot load mixer controls: Invalid argument
If anyone wants to check this issue, should you need any type of info
regarding this, please do not hesitate asking, I will post anything you
require.
PS: I don't think it is really necessary to say either but I don't expect
anyone to force-commit to this either, I mainly want to know if there is a
solution to this or if reporting this issue I can help to get it fixed.
Thanks for your time.

This device reports that it supports two channels.
What makes you think that you can play eight channels?

These are bugs in the device firmware. However, the driver could
handle them better.

Hello,
Forgive my ignorance if I'm totally wrong, what made me think that is 7.1
capable is:
The headset is made to emulate 7.1 sound in headphones, that it does
through the sound card it provides.
Also the aplay output...
aplay --dump-hw-params returns CHANNELS: [2 8]
and "aplay -L" output also reports:
surround71:CARD=Elite,DEV=0
SteelSeries Siberia Elite, USB Audio
7.1 Surround output to Front, Center, Side, Rear and Woofer speakers
With the manufacturer driver under other OS's you do select 7.1 setup and
then you plug the specific headphones to the soundcard and can hear the
surround sound, but I don't mean to compare though, just that it also made
me believe this hardware supports 7.1
Thanks for your time.

You need workaround since pulseaudio don't like volume control with more
than two channels

Can you post output of your usb audio device ?

Bit map indicating which mixing Controls are programmable.
>> >> > bmControls 0x00
>> >> > bmControls 0x00
The Mixer Unit Descriptor reports which Controls are programmable in the
bmControls bitmap field. This bitmap must be interpreted as a
two-dimensional bit array that has a row for each logical input channel and
a column for each logical output channel. If a bit at position [u, v] is
set, this means that the Mixer Unit contains a programmable mixing Control
that connects input channel u to output channel v. If bit [u, v] is clear,
this indicates that the connection between input channel u and output
channel v is non-programmable. Its fixed value can be retrieved through the
appropriate request. The valid range for u is from one to n. The valid
range for v is from one to m.
The bmControls field stores the bit array row after row where the MSb of
the first byte corresponds to the connection between input channel 1 and
output channel 1. If (n x m) is not an integer multiple of 8, the bit array
is padded with zeros until an integer number of bytes is occupied.
The number of bytes used to store the bit array, N, can be calculated as
follows:
IF ((n x m) MOD 8) <> 0 THEN
N = ((n x m) DIV 8) + 1
ELSE
N = ((n x m) DIV 8)
Index of a string descriptor, describing the name of the first logical
channel.

In case this can be of any useful info, in the form of unknown controls
reported by the lsusb output, manufacturer software in other OS has
controls for:
* dolby surround activation (off and on).
* microphone input volume (which works fine now) in snd_usb_audio
* microphone input "compression" (supposedly to keep input within certain
non distorting levels)
* input noise reduction (off and on too)
* micro retro feedback volume
* equalizer.
Thanks for your time.

Take a look at 4.7.2.6 Mixer Unit Descriptor of USB Audio 2.0 specs
Do the sound card work with alsa when you force the driver to skip
build_mixer_unit_ctl() for unitid 10 ?
Can alsamixer change the 8 channels speaker playback volume control ?
You can add usb_audio_info to dump those values of the AudioControl
Interface Descriptor with unitid 10
https://git.kernel.org/cgit/linux/kernel/git/tiwai/sound.git/tree/sound/usb/mixer.c
for (; ich < num_ins; ich++) {
int och, ich_has_controls = 0;
for (och = 0; och < num_outs; och++) {
__u8 *c = uac_mixer_unit_bmControls(desc, state->mixer->protocol);
+ usb_audio_info(state->chip, " bmControls [%d,%d] : %x\n", ich, och, *c);
if (check_matrix_bitmap(c, ich, och, num_outs)) {
ich_has_controls = 1;
break;
}
}
+ if (state->chip->usb_id == USB_ID(0x1038,0x1225))
+ if(unitid == 10)
+ ich_has_control = 0;
if (ich_has_controls)
build_mixer_unit_ctl(state, desc, pin, ich,
unitid, &iterm);
}
}
return 0;
}

You need to find out the terminals of two inputs if you want to know the
function of this mixer unit
> bUnitID 10
> bNrInPins 2
> baSourceID( 0) 9
> baSourceID( 1) 1
There are debug output in the system log when you compiled the driver with
debug option
usb_audio_dbg(state->chip, "[%d] MU [%s] ch = %d, val = %d/%d\n",
cval->head.id, kctl->id.name, cval->channels, cval->min, cval->max);
Is the suffix "Volume" correct since it may be just a mute switch ?
3.13.4 Mixer Unit
The Mixer Unit (MU) transforms a number of logical input channels into a
number of logical output channels. The input channels are grouped into one
or more audio channel clusters. Each cluster enters the Mixer Unit through
an Input Pin. The logical output channels are grouped into one audio
channel cluster and leave the Mixer Unit through a single Output Pin. Every
input channel can virtually be mixed into all of the output channels. If n
is the total number of input ixer channels and m is the number of output
channels, then there is a two-dimensional array (n · m) of M Controls in
the Mixer Unit.
Not all of these Controls have to be physically implemented. Some Controls
can have a fixed setting and be non-programmable.
The Mixer Unit Descriptor reports which Controls are programmable in the
bmControls bitmap field. Using this model, a permanent connection can be
implemente d by reporting the Control as non-programmable in the bmControls
bitmap and by returning a nnection can be implemented by Control setting of
0 dB when requested. Likewise, a missing (muting) co reporting the Control
as non-programmable in the bmControls bitmap and by returning a Control
setting of –∞ dB. A Mixer Unit MUST respond to the appropriate Get Request
to allow the Host to retrieve the actual settings on each of the (n · m)
Mixer Controls.
4.7.2.6 Mixer Unit Descriptor
The bmMixerControls field stores the bit array row after row where the MSb
of the first byte corresponds to the connection between input channel 1 and
output channel 1. If (n · m) is not an integer multiple of 8, the bit array
is padded with zeros until an integer number of bytes is occupied.
The number of bytes used to store the bit array, N, can be calculated as
follows:
IF ((n * m) MOD 8) <> 0 THEN
N = ((n * m) DIV 8) + 1
ELSE
N = ((n * m) DIV 8)
The bmControls field contains a set of bit pairs, indicating which Controls
are present and what their capabilities are. If a Control is present, it
must be Host readable. If a certain Control is not present then the bit
pair must be set to 0b00. If a Control is present but read-only, the bit
pair must be set to 0b01. If a Control is also Host programmable, the bit
pair must be set to 0b11. The value 0b10 is not allowed.

Hello,
The device has 3 inputs as you will see in the picture I attach.
Two analog inputs and 1 digital:
* Analog micro
* Analog headphones
* USB input <-- This is how the headphones are plugged to have dolby
surround enabled and some of illuminations settings (the headphones can
have multiple illumination colors, I mention this as means to be able to
identify possible unknown switches the device may have).

Do you mean there is no sound using alsa hw device since pulseaudio does
not support the multichannel speaker playback volume comtrol ?
speaker-test -c8 -t wav -D hw:CARD=Elite
speaker-test -c2 -t wav -D hw:CARD=Elite
You need to know how to compile alsa driver for you running kernel if you
want to fix the problem

If alsamixer or amixer cannot set the speaker playback volume
Try skip the problematic PCM Volume controls by adding
if (state->chip->usb_id == USB_ID(0x1038,0x1225))
if(unitid == 10)
ich_has_control = 0;
If the driver really need this mixer unit for the playback path, you need
to fix those controls
bUnitID 10
bNrInPins 2
baSourceID( 0) 9 microphone
baSourceID( 1) 1 usb streaming
This look like the first four problematic controls related to microphone
and the last control related to streaming

Hello,
when I run the tests:
speaker-test -c8 -t wav -D hw:CARD=Elite
speaker-test -c2 -t wav -D hw:CARD=Elite
I only get sound from front left and front right channels.
About compiling the alsa driver in my running kernel or where to place the
code you mention, well, as much as I have tried, my lack of experience has
resulted in failing, although I'm still trying...
I have tried with latest kernel 3.18.10, and kernel 4.0-rc5.
Maybe I'm asking too much, can you provide a mixer.c or all the files I
need to substitude in any kernel version you decide?, I'll just download
the source for that kernel and merge with the file/s you attach and compile
the whole thing, of that I'm sure I can do.
If it's too much I'm asking , don't worry, I'm still trying.
