Howto set ALSA output device in MythTV?

[agkbill]

Hi,


I have a 4.0 loudspeeker configuration that I would like to use playing DVD in mythtv.






When I look at "aplay -L" I get following.




christer@gentoo_ce ~ $ aplay -L
null
Discard all samples (playback) or generate zero samples (capture)
default:CARD=EMU1010
E-mu 1010 [MAEM8810], ADC Capture/Standard PCM Playback
Default Audio Device
front:CARD=EMU1010,DEV=0
E-mu 1010 [MAEM8810], ADC Capture/Standard PCM Playback
Front speakers
rear:CARD=EMU1010,DEV=0
E-mu 1010 [MAEM8810], ADC Capture/Standard PCM Playback
Rear speakers
center_lfe:CARD=EMU1010,DEV=0
E-mu 1010 [MAEM8810], ADC Capture/Standard PCM Playback
Center and Subwoofer speakers
side:CARD=EMU1010,DEV=0
E-mu 1010 [MAEM8810], ADC Capture/Standard PCM Playback
Side speakers
surround40:CARD=EMU1010,DEV=0
E-mu 1010 [MAEM8810], ADC Capture/Standard PCM Playback
4.0 Surround output to Front and Rear speakers
surround41:CARD=EMU1010,DEV=0
E-mu 1010 [MAEM8810], ADC Capture/Standard PCM Playback
4.1 Surround output to Front, Rear and Subwoofer speakers
surround50:CARD=EMU1010,DEV=0
E-mu 1010 [MAEM8810], ADC Capture/Standard PCM Playback
5.0 Surround output to Front, Center and Rear speakers
surround51:CARD=EMU1010,DEV=0
E-mu 1010 [MAEM8810], ADC Capture/Standard PCM Playback
5.1 Surround output to Front, Center, Rear and Subwoofer speakers
surround71:CARD=EMU1010,DEV=0
E-mu 1010 [MAEM8810], ADC Capture/Standard PCM Playback
7.1 Surround output to Front, Center, Side, Rear and Woofer speakers
iec958:CARD=EMU1010,DEV=0
E-mu 1010 [MAEM8810], ADC Capture/Standard PCM Playback
IEC958 (S/PDIF) Digital Audio Output
christer@gentoo_ce ~ $



From that list I would like to use the

surround40:CARD=EMU1010,DEV=0
E-mu 1010 [MAEM8810], ADC Capture/Standard PCM Playback
4.0 Surround output to Front and Rear speakers

settings.


But how do I set that in MythTV?

I can not find anything under audio settings coresponding to aplay -L output.

Now in mythtv I got.

* default
* spdif
* surround51
* analog
* digital
* mixed-analog
* mixed-digital
* hdmi
* plughw:0.3
* NULL



Any ideas?

Best regards,
