[Alsa-user] How to get rear speakers working on ens1371

[Rajesh The Great]

Hello ,

I use RedHat 7.2. I have Creative Sound Blaster128 (es1371) sound card built into my mother board.Line In and Line Out are multiplexed in the mother board. I mean to say the "rear out" jack and "line in" are the same in my motherboard . The card is supposed to have 4 channels. I have creative inspire 4.1 speakers.

I have no problems in windows as I can enable the rear speakers by choosing quadrophonic speakers in the advanced audio properties. ( I have to use the "direct-sound" interface provided by directX to actually get rear speakers working on win98 but on winXP I dont need to do anything the rear speakers work all the time ) Ok .. I am hearing ur replies - "Who cares ?" ..

But in Linux I can hear through only 2 speakers (the front ones) and the base spearker ( the subwoofer ). Is there any way to get all 4 Speakers working in Linux ?

I read on some forum that installing ALSA could help . I have Installed ALSA 0.9rc2, without any benefits. Have I not configured it properly? The module I have been using is snd-ens1371.

I have tried all mixers including OSS mixers and gamix,alsamixer ( ALSA mixers ) without any benefits. All mixers seem to recongnise Line as "record" or "cpature" device. ( yeah .. one mixer is same as another! )

I have tried different distros too ( RedHat 7.1, RedHat 7.2, RedHat 8, Mandrake 8.2 etc.. ) but all distros i've used have the same problem.
Also Linux recognises my soundcard as "Sound Blaster PCI128 / Esonique Audio PCI" or something like that , is that relevent ?

The module snd-ens1370 seems to support " LineIn to AOUT " as I saw on alsa-driver/alsa-kernel/pci/ens1370.c ... But snd-ens1371 has no such option ... Why is it??

I tried copying the snd1370 LineIn to AOUT stuff onto snd1371 specific code - recomplied - and loaded the recompiled module .. But this doesnt work either ...

I've even tried installing windows drivers of my sound card under wine ( I know it sounds stupid ... But I was desperate to get rear speakers working ).

Someone suggested that even the player Should support 4 speaker setup and that I install mplayer ( A player that is suppose to support multiple channels. )

I downloaded and installed mplayer . I tried playing some songs and .... It still plays only on two speakers . I have installed ALSA and i tried the option mplayer -ao alsa9 but mplayer simply quits saying

couldn't open/init audio device -> no sound
Audio: no sound!!!
Video: no video!!!

Have I not configured alsa correnctly . lsmod reports snd-* loaded properly and "/etc/init.d/alsasound status" reports ALSA is up and running

I've also tried mplayer -af channels=4:0:2:1:3 ... That does not work either ....
How do I get mplayer ( or is it ALSA ) to put sound on my rear spkrs ...

I am having this problem since a long time and (sic) it deters me from booting into Linux !

Is there any hope for me to get all 4 speakers working under Linux ?

Thank You
