emu10k1 multichannel issue/observation

[Rick Wright]

Hi Lee,

I've been using your multichannel patch (actually mainstream now..) to
this driver for several months and it works great.  I was using a
somewhat old (~2 yrs now) version of the Audigy2 ZS Platinum Pro card
w/external chassis.  One thing I never got working was the 7.1 side
channels.  I was never able to see/turn on Side Ch sliders in AlsaMixer
and could never find a playback port(s) to get sound out.  These
channels just didn't seem supported.

Fast-forward to about a month ago and I built another machine and bought
another identical Audigy2 ZS Platinum Pro sound card w/chassis and the
AlsaMixer sliders for the side channels (driver support?) appeared
immediately and I have verified that pcm_playbacks 15 & 16 are the L/R
Side channels, respectively.  As a test, I swapped the sound cards
between two identical machines and the sliders followed the new card.
Appearing where they never had before and disappearing from the machine
originally hosting the new card.

My questions are:
1) Was there an early version(s) of this card where the side channels
aren't supported by the ALSA driver?
2) Could this be made to work?
3) If so, what info is needed and who needs it?



Additionally, at some point in recent time, there is a minor new problem 
where upon initial boot (I think, but can't swear this is 100% 
reproducable) there is low level noise on all outputs.  The fix is to 
unplug/replug the firewire-ish cable that connects the external chassis 
to the PCI card.  This always eliminates the static.  Could this be a 
problem with the card's initialization?



Thanks,
Rick

Possible.

Yes.

Please provide lspci output for the new card (working side channels) and
the old one (non working side channels).

Attached are the outputs of lspci for both working/non-working side 
channel machines.

These machines are basically clones and the Audigy2 card is in the same 
PCI slot in both machines.

Let me know how else to help.

Sorry I should have been more specific.  I need 
"lspci -vn | grep -A1 0401" output for both machines.

The driver currently detects the card with the non-working side channels
as an Audigy 2 EX.  Is this correct?  Do you know whether all Audigy2 EX
cards have side channels?

Anyway, here's a patch to enable the side channels.

Enable side surround channels for Audigy2 EX.  Tested by Rick Wright

Lee,

I've given you some incorrect information about the card with the 
non-working side channels.  My appologies.  However, there is still 
value to all of this.

The older card is an Audigy2 Platinum eX (model: SB0280) 
(http://www.digit-life.com/articles2/creative-audigy2-platinum-ex/index.html), 
not an Audigy2 Platinum Pro ZS (model: SB0360) as I previously 
reported.  This card appearently was the predecessor to the Platinum Pro 
ZS, complete with identical external chassis, etc. - leading to my 
incorrect model assumption.  This makes sense considering I knew this 
was a dated card, but top-of-the-line when purchased.  I appologize for 
not checking explicitly before reporting the issue.  There is an article 
on the ZS release with an excellent comparison photo of my 2 cards here: 
http://www.digit-life.com/articles2/creative-audigy2-zs/

That said, this Platinum eX card is a 6.1 channel card where there is a 
"center rear" channel (mono) in addition to the typical 5.1 channels.  
This "standard" was an intermediate step to 7.1, as you probably know.  
So now my reported "problem" has shifted from "why can't I see my PCM 
Side channel volume controls?" to "why doesn't the PCM Center Rear 
volume slider appear?"


I've just tested your patch, here are the results:

The new (1.0.10rc2) patched alsa-driver detects this card as an "Audigy 
2 EX [1005]".  There are still no PCM Side channel sliders (though now 
we know the card doesn't support these), which suprises me since that 
was the patch, no?  At any rate, the patch should be changed to remove 
7.1 and add 6.1, assuming there is support for this.  I would expect a 
"PCM Center Rear" volume slider to appear and be functional for this card.

FYI, The ZS Platinum Pro card is detected as an "Audigy 2 ZS [2001]" in 
my other identical machine with the latest FC4 ALSA (1.0.9rf) installed 
via yum/rpm.  Looking at the source file your patch was applied to, I 
didn't see an entry specific to this card model.  If there should be a 
configuration entry specific to the ZS Platinum Pro (SB0360), I'd be 
happy to help by providing all necessary info/test results.  Please let 
me know.  This also applies for the Platinum EX model (SB0280).

Observation:  with the FC4 ALSA version, I noticed that upon initial 
boot with both of these cards (i.e. both machines), there would usually 
be a low level noise (hiss) coming from all output channels.  The fix 
for this was to unplug/replug the firewire-type connector to the 
external chassis and then the noise was gone - 100% success rate.  I'm 
curious as to whether this was a known issue in my dated version of ALSA 
and if this has been fixed.  It seemed to me like a problem with the 
first initialization, but the unplug/replug forced a successful 
initialization?  I've only rebooted once since upgrading my alsa-driver 
with your patch and I haven't noticed the low level hiss.

Lastly, there is one remaining annoyance common to both of these cards 
where the L/R output volume controls (sliders) are backwards wrt a 
standard 1/8" stereo-to-RCA's (red/white) cable.  I reported this 
behavior to the alsa-bugtracker back in Feb 
(https://bugtrack.alsa-project.org/alsa-bug/view.php?id=904), though now 
it appears I had the card model wrong...  This bug report is still 
open.  This behavior persists (on at least the EX card) through the 
latest version (1.0.10rc2) downloaded, patched, and tested today.  I 
know this is minor and my fix has been simply plugging the RCA cables in 
backwards, but shouldn't this work properly?  Until this testing today, 
I've been using a stock FC4 system/ALSA install, but if this is a 
configuration error on my end would you please advise?


Sorry for the long mail, but I wanted to cover everything I've noticed 
and be thorough.  I look forward to your input.

Rick
