EMU10K1.conf

Hi,

I finally got my emu10k1 soundcard working with full 5.1 surround :-)

It took me 2 days, getting alsa to know and sound working properly. I finally found out that /usr/share/alsa/cards/EMU10K1.conf was b0rked and modified it so everything now works properly. Things which prevented it from working properly were:

- Rear/Center&&LFE Volume Controls in the config file were set to 0 and
locked!..

- surround51 was statically bound to the non-digital output and locked
(to the analogue output), so there was no way to get surround sound on my digital-out.

- other volume controls were locked too, I had a look at Audigy.conf
and reduced the locked controls to the minimum required.

The patch attached for /usr/share/alsa/cards/EMU10K1.conf is actually very trivial and a cleanup of the old file, it would be cool if you'd apply the patch to the ALSA config file in CVS, I'm sure it would help a lot of people which have no rear sound with the emu10k1.

/me now leans back and enjoys alsa and Lord Of The Rings II Extended Version in _FULL_ Digital Dolby 5.1 :))))

best wishes,
dominik.

"Wave XXX Volume" controls should be zero for multi-channel outputs indeed, because these are volumes of signals duplicated from the front channel to surround/center/lfe channels.
locking could be optional, though.

hmm, i'm not sure about this. surround51 was designed for outputs from three analog jacks.

what do you get from digital out with surround51? does the card send non-encoded raw 6-channel PCM over spdif?

on Audigy, the signal routing and control elements are fairly different from SB Live. so, you cannot copy it simply...

Hi!

For me "Wave XXX Volume" controls (using digital out) work like intended:

Wave: Front Speakers Volume
Wave Center: Center Speaker
Wave LFE: LFE
Wave Surround: Rear Speakers

But setting "Wave Surround Playback Volume" to 0 in the EMU10K1.pcm.rear.0 section has the effect that no sound is coming out of the rear boxes.

And setting "Wave Center Playback Volume" and "Wave LFE Playback Volume" to 0 (in EMU10K1.pcm.center_lfe.0) has the effect that no sound is coming out of the center and LFE speakers.

Generally this means that with the current alsa configuration only the 2 front speakers have sound (when using the digital out jack).

By removing the locks and 0-settings, its possible to control the other volumes too -> and thus unlocking the other speakers too. :)

With the modified config-file and setting xine to use surround51 I get True surround 5.1 sound. I have a 5.1 test-audio file, which I used for testig - Its not just duplication of the front speakers signal.

Using the unmodified config and setting xine to use surround51, the card switches to analogue out, the receiver blinks (no connection) and nothing happens. If I remove the analogue-out lock in the config, only the 2 front speakers work. Removing the 0 volume locks (and increasing volumes in the mixer) everything works.

No, digital out sends the data over this creative-coaxial cable. AFAI understand, spdif is only (?) used for sending raw Encoded AC3 data to a 5.1 receiver in order to let the receiver decode it.

I didn't copy the routing part, I just inspired :-) myself in the Audigy.conf files. For the audigy digital-out and the other volumes weren't locked and set to 0; so I tried this out for the EMU10k1 too and it worked :D

I hope this helps a bit!
dominik.

At Tue, 06 Jan 2004 12:23:35 +0100,

did you raise "Surround Digital Playback" volume?
(not "Surround", it's an entry of AC97).

also "Center Playback" and "LFE Playback" volumes?

the switch of "SB Live Analog/Digital" can be removed if it works for you. it was set to make sure the center "analog" jack works. (in the recent models, the digital out is shared with the center/lfe jack.)
with my emu10k1 board, i don't get any valid signals over center/digital jack unless AC3 is played. it might depend on the receiver. perhaps creative has its own protocol?

but, anyway, "Wave Surround" and "Wave Center" don't make sense at all. they are volumes of duplicated signals. the volumes of surround/center/lfe channels are different mixer elements.

also, if you want to send AC3 via spdif, you should use iec958 (aka spdif) in xine.

Hi,

I just rechecked everyting. You're right, it's just the "SB Live Analog/Digital" switch/lock to "0" in EMU10K1.conf which needs to be removed, to make things work. (I'm using a Creative Cambridge SoundWorks DTT3500 receiver, my sblive/emu10k1 card has revision 07 (lspci))

As you pointed out, using the surround/center/lfe/wave volume controls everything can be controlled. The WAVE* volume controls-stuff isn't neccessary.

So basically it boils down to...

ok, then i'll comment out this part on the cvs.

thanks for the confirmation.
