[Alsa-user] ESI Gigaport HD USB

[Simon B. <S.B...@sb...>]

Hi,

I'm using a ESI Gigaport HD (USB), with the snd-usb-audio driver and 
PulseAudio. The card is run in 8ch mode @ 44100 Hz on an USB 2.0 bus.

The card already works quite fine, except for the rear *right* speaker, all 7 
other speakers, including the rear *left*, work. The rear right speaker stay 
mute all the time. volume settings, muteing/unmuting, has no effect.

My speaker setup is as follows:
port / speaker
1 = front right
2 = front left
3 = rear right
4 = rear left
5 = center
6 = LFE
7 = side left
8 = side right

ports 7 and 8 seem to be swapped somehow.... (don't care much)
port 4 / rear right stays dead.

I found the port-to-speaker-mapping by experimenting. So to be honest, since I 
never hear a tone from port 4, I can't for sure say that port 4 is actually 
rear right, but since no port remain (except for headphones), I assume that 
this is correct. :-)

I'm using the most up-to-date alsa driver package
"alsa-driver-1.0.21.0.gbed43.13.g15db1" (2009-10-09)
and kernel-2.6.31.1 (x64).

Ist this problem already known?
May I be of any help in debugging it?

Thanks ahead.
