I am bit confused about what you said here, so can you please detail a bit more what you mean when you say "when you have optical in on your receiver, you can go directly from the USB audio plug"? :confused2:
There is no HDMI input on my receiver so I will need to find a way how I can get the digital signal to it using either the optical or coaxial inputs...
Any ideas are appreciated.
Hi,
I had the same problem as you. My AV Receiver is not HDMI capable so I order a usb to spdif converter like this one:
http://cgi.ebay.com/ws/eBayISAPI.dll?Vie...0338005136
When pluged in the Revo, it gives a new audio card (with only spdif capability):
lsusb
Bus 002 Device 003: ID 09ef:0101 Xitel MD-Port DG2 MiniDisc Interface
aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: NVidia [HDA NVidia], device 0: ALC662 Analog [ALC662 Analog]
Subdevices: 1/1
Subdevice #0: subdevice #0
card 0: NVidia [HDA NVidia], device 3: NVIDIA HDMI [NVIDIA HDMI]
Subdevices: 1/1
Subdevice #0: subdevice #0
card 1: DG2 [MD-PORT DG2], device 0: USB Audio [USB Audio]
Subdevices: 0/1
Subdevice #0: subdevice #0
To use it, that was a little bit tricky for me. I eventually found the solution by directly changing the default card in the alsa conf.
In /usr/share/alsa/alsa.conf
Change :
defaults.ctl.card 0
defaults.pcm.card 0
To :
defaults.ctl.card DG2
defaults.pcm.card DG2
I could have use 1 in place of DG2 (which is the alias for my usb card, but like this, if the number changes, it still works)
In XBMC, I let the default/iec958 option and just enabled digital output (and DTS/Dolby Digital of course).
That works perfectly for now (meaning till I have enough to buy a HDMI AV Receiver
)The only drawback I now have with the Revo is subtitle display that doesn't always work with VDPAU (although it then works with auto, but the atom can't then decode the video
).Regards,
