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

Drive

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...

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

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 WAV file(s) ALSA lib setup.c:565:(add_elem) Cannot obtain info for CTL elem (MIXER,'Headphone Center Playback Switch',1,0,0): No such file or

directory

...

Playback open error: -2,No such file or directory

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

slave.channels 6
ttable.0.0 1
ttable.1.1 1
ttable.2.2 1

speakers" device $DEV }

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.

thanks,
