[RFC Patch] ALSA - EMU10K1 - Remove Center LFE Wave Center and Wave LFE control for SB Live! Platinum

[-- Attachment #1: Type: text/plain, Size: 719 bytes --]

SB Live! Platinum CT4760P is just a 4 channels sound card with STAC9721 and
Philips UDA1334 DAC

Is it feasible to remove "Center" , "LFE", "Wave Cetner" and "Wave LFE"
Playback Volume control ?

or add a bitmap to disable the creation of those controls

Anyone know whether this patch has any side effect for the user with  Live
Drive

AFAIK, speaker-test will fail

speaker-test -d -c 6 -t wav -Dsurround51:1

speaker-test 1.0.24.2

Playback device is surround51:1
Stream parameters are 48000Hz, S16_LE, 6 channels

ALSA lib setup.c:565:(add_elem) Cannot obtain info for CTL elem

The side-effect is that opening surround51 would spew annoying error
messages as you've seen.  It should return an error without much
complaint.

I'm not sure what is the best way to solve it.
Defining another conf such as EMU10K1-4ch.conf would be an option,
but it's not elegant...


thanks,

Takashi

The side effect is not related to my patch but exout

#define EXTOUT_HEADPHONE_L 0x06 /* LiveDrive - Headphone - left */
#define EXTOUT_HEADPHONE_R 0x07 /* LiveDrive - Headphone - right */

I just follow Documentation/ALSA-Configuration.txt to set extout to 0x1f03
for my SB Live! Platinum without Live! Drive

As Philips UDA1334 has no hardware volume control

The problem is pulseaudio expect the Front Channel and Rear Channels volume
controls have same dB range

The point is those 4.1 speakers for SB Live!, SB Live! Platinum and SB Live!
Value only have green jack and blue jack,  the signal of the Subwoofer is
produced from the those jacks

it seem that the device "surround41" is only for SB Live! 5.1 in alsa

OK, I overlooked that the problematic controls are "Headphone XXX".
These should be marked as optional in the card config.
I fixed this now.

Meanwhile, as no obvious problem is found in your patch, I applied it
now.
