 |
|
Hi there,
I'm trying to build up a HTPC (Zotac IONITX U-E board with Atom D-525). At the moment I ran into some trouble to get an audio output via HDMI. First the config:
| aplay -l: | **** List of PLAYBACK Hardware Devices ****
card 0: Intel [HDA Intel], device 0: ALC662 rev1 Analog [ALC662 rev1 Analog]
Subdevices: 1/1
Subdevice #0: subdevice #0
card 0: Intel [HDA Intel], device 1: ALC662 rev1 Digital [ALC662 rev1 Digital]
Subdevices: 1/1
Subdevice #0: subdevice #0
card 1: NVidia [HDA NVidia], device 3: HDMI 0 [HDMI 0]
Subdevices: 1/1
Subdevice #0: subdevice #0
card 1: NVidia [HDA NVidia], device 7: HDMI 0 [HDMI 0]
Subdevices: 1/1
Subdevice #0: subdevice #0
card 1: NVidia [HDA NVidia], device 8: HDMI 0 [HDMI 0]
Subdevices: 1/1
Subdevice #0: subdevice #0
card 1: NVidia [HDA NVidia], device 9: HDMI 0 [HDMI 0]
Subdevices: 1/1
Subdevice #0: subdevice #0 |
With aplay I figured out, device 1.7 gives me sound over HDMI. The other devices (1.3 / 1.8 / 1.9) remain quiet. Hence I specified the output device via asound.conf
| /etc/asound.conf: |
pcm.!default {
type hw
card 1
device 7
}
|
But these lines seem to be useless. At least mplayer doesn't play sound with:
I can get sound over HDMI only with the command line:
| Code: | | mplayer -ao alsa:device=hw=1.7 |
Within XBMC the situation seems to be even more queer:
Without any configuration I can hear the ticking sound when switching to options. Playing any movie or music there's no chance to get sound over HDMI. I've tried every combination in the audio settings:
| Code: | Audio: hdmi
Audio device: HDMI, HDMI Alsa, HDMI Nvidia, HDMI Standard, Custom (alsa:...)
Pass-through: HDMI, HDMI Alsa, HDMI Nvidia |
I could image that XBMC lacks of any dts or ac3 pass-through codecs. But via Toslink (iec958) any sound works perfectly.
On the other hand: CMUS works and plays every MP3 via HDMI without any problems. Selected output device is just: alsa - no additional option needed.
My goal would be:
- create an /etc/asound.conf that makes the HDMI device as default sound output. Analog output is not needed.
- Use HDMI audio in XBMC, CMus and mplayer without any special parameters - just the default audio.
Is that possible? What do I have to do? |

| "default" is basically "surround20" - i.e. 2 speakers. Do the same for surround51 and surround40. Have many speakers have you got? |

Ok, I haven't got it yet completely. So, default ist just for surround20. Does it mean: For DTS sound I have to specify the numbers of speakers explicitly and not take just any kind of pass-through?
Hardware configuration:
- Speakers are a 5.1 system connected to a Marantz AV-receiver
- My PC has an optical output (S/PDIF) and a HDMI output (Nvidia ION).
- To the optical output is the AV-receiver connected which is able to decode DTS and AC3.
- To the HDMI output is the TV connected. It can decode AC3 but not DTS.
- I want to be able to connect the AV-receiver via HDMI too.
Current state:
- XBMC plays everything through S/PDIF, but only the system sounds via HDMI. Until now I didn't find any solution to change that behavior.
- CMus plays MP3 to HDMI by default, if X had been started.
- VDR plays (Stereo) to HDMI.
- mplayer plays to HDMI, when I specify the command-line: mplayer -ao alsa:device=hw=1.7
What I want to have:
- Pass-through any AC3 or DTS sound to both HDMI and S/PDIF.
- Play any other sound through HDMI and S/PDIF too.
- Solution should be application-independent and independent of the number of speakers. Means, just specify alsa without any additional options.
Is that possible with an asound.conf solution? |
