I was wondering if anyone has any hints, or could help me figure out how to get the Zalman ZM-RSSC v2 USB 5.1 sound card to work with my XBMC Ubuntu box.

So far I've gone through these steps:
1. Disabled on-board sound
2. Plugged in the USB Drive, booted up and changed to a different terminal and upgraded ALSA using the upgrade script here
3. Then I checked what is being detected by entering "aplay -l" and "aplay -L".
I do this from the xbmc user. When trying these commands from my root user nothing is detected... which is probably a good indication that things aren't going well?

aplay -l gives:

Code:

**** List of PLAYBACK Hardware Devices ****
card 1: default [USB Sound Device         ], device 0: USB Audio [USB Audio]
   Subdevices: 1/1
   Subdevice #0: subdevice #0

aplay -L gives:

Code:

front:CARD=default,DEV=0
    USB Sound Device        , USB Audio
    Front speakers
surround40:CARD=default,DEV=0
    USB Sound Device        , USB Audio
    4.0 Surround output to Front and Rear speakers
surround41:CARD=default,DEV=0
    USB Sound Device        , USB Audio
    4.1 Surround output to Front, Rear and Subwoofer speakers
surround50:CARD=default,DEV=0
    USB Sound Device        , USB Audio
    5.0 Surround output to Front, Center and Rear speakers
surround51:CARD=default,DEV=0
    USB Sound Device        , USB Audio
    5.1 Surround output to Front, Center, Rear and Subwoofer speakers
surround71:CARD=default,DEV=0
    USB Sound Device        , USB Audio
    7.1 Surround output to Front, Center, Side, Rear and Woofer speakers
iec958:CARD=default,DEV=0
    USB Sound Device        , USB Audio
    IEC958 (S/PDIF) Digital Audio Output
null
    Discard all samples (playback) or generate zero samples (capture)

When I run speaker-test -D default -c 6 I also have to do so with sudo otherwise I get permission denied problems. When it runs I am only hearing the static through left and right speakers.

Finally I am also using a .asoundrc file that I placed in both home directories of my xbmc user and my root user. It looks like this:

Code:

Set default sound card
# Useful so that all settings can be changed to a different card here.
pcm.snd_card {
     type hw
     card 1
}

pcm.dmix6 {
     type dmix
        ipc_key 1024
        ipc_key_add_uid false # let multiple users share
        ipc_perm 0660 # IPC permissions (octal, default 0600)
        slave {
                pcm snd_card # see below
                rate 48000
                channels 6
                period_time 0
                period_size 1024
                buffer_time 0
                buffer_size 4096
        }
     }

    type route

    ttable.1.1 1
}

pcm.ch31dup {
    type route
    slave.pcm "dmix6"
    slave.channels 6
    ttable.0.0 1

        ttable.0.4 0.5
        ttable.1.4 0.5

}

        ttable.1.1 1

        ttable.0.4 0.5
        ttable.1.4 0.5
        ttable.0.5 0.5
        ttable.1.5 0.5
   }


pcm.duplex {
     type asym
     playback.pcm "ch51dup"
#     playback.pcm "dmix2"
#     capture.pcm "mydsnoop"
     capture.pcm "snd_card"
}

From a fresh reboot that goes into XBMC when I try and play anything I just get an error saying "Failure to initialize audio device". I hope someone sees something obvious I'm doing wrong :o
