OK I have a ASRock with Ubuntu & XBMC installed on it.

I got everything working good, but i am having an issue getting the HDMI & L/R audio working.

With my ASRock I had an issue with HDMI audio and crossfading MP3 tracks. so i used this .asoundrc (thanks to kingmos)

Code:

# ~/.asoundrc or /etc/asound.conf
# ALSA configuration file

##### USAGE #####
# Save this file as "~/.asoundrc" (for user-specific sound configuration) or
# "/etc/asound.conf" (for system-wide sound configuration) and specify ALSA
# device names ad described in the next section.


##### DEVICE NAMES #####
# This configuration file defines four devices for use by the user.  Those
# devices are "analog", "mixed-analog", "digital", and "mixed-digital".  The
# user may also re-define "default" to be identical to one of the above-named
# devices (i.e. to send all sound output to the digital output unless otherwise
# specified).  Use the device names as described below:
#  - "analog" outputs to the analog output directly and (at least on software
#  sound cards) blocks other audio output.  After playback completes, "queued"
#  sounds are output in sequence.
#  - "mixed-analog" mixes audio output from multiple programs into the analog
#  output (so you can hear beeps, alerts, and other noises while playing back
#  an audio stream).
#  - "digital" outputs to the digital output directly.  Since most (all?)
#  digital outputs expect 48kHz PCM audio, this may not work for some playback
#  (i.e. CD's--which are 44.1kHz PCM audio--or 32kHz audio streams from TV
#  recordings, etc.).
#  - "mixed-digital"

# All other devices created within this file are used only by the configuration
# file itself and should /not/ be used directly.  In other words, do not use
# the devices "analog-hw", "dmix-analog", "digital-hw", or "dmix-digital".


##### IMPORTANT #####
# To make this ALSA configuration file work with your sound card, you will need
# to define the appropriate card and device information for the "analog-hw" and
# "digital-hw" devices below.  You can find the card and device information
# using "aplay -l".


##### Configuration File #####

# Override the default output used by ALSA.  If you do not override the
# default, your default device is identical to the (unmixed) "analog" device
# shown below.  If you prefer mixed and/or digital output, uncomment the
# appropriate four lines below (only one slave.pcm line).
#
# Note, also, that as of ALSA 1.0.9, "software" sound cards have been modified
# such that their default "default" device is identical to the "mixed-analog"
# device.  Whether using an ALSA version before or after 1.0.9, it does no harm
# and has no affect on performance to redefine the device (even if the
# redefinition does not change anything).  Also, by using this ALSA
# configuration file, you once again have access to unmixed analog output using
# the "analog" device.
pcm.!default {
  type plug
## Uncomment the following to use (unmixed) "analog" by default
#  slave.pcm "analog-hw"
## Uncomment the following to use "mixed-analog" by default
#  slave.pcm "dmix-analog"
## Uncomment the following to use (unmixed) "digital" by default
#  slave.pcm "digital-hw"
## Uncomment the following to use "mixed-digital" by default
  slave.pcm "dmix-digital"
}

# Control device (mixer, etc.) for the card
ctl.!default {
  type hw
  card 0
}

# Alias for (converted) analog output on the card
# - This is identical to the device named "default"--which always exists and
# refers to hw:0,0 (unless overridden)
# - Therefore, we can specify "hw:0,0", "default", or "analog" to access analog
# output on the card
# - Note that as of ALSA 1.0.9, "software" sound card definitions redefine
# "default" to do mixing, meaning this device is different from "default" and
# allows playback while blocking other sound sources (until playback
# completes).
pcm.analog {
  type plug

# Alias for (converted) mixed analog output on the card
# - This will accept audio input--regardless of rate--and convert to the rate
# required for the dmix plugin (in this case 48000Hz)
# - Note that as of ALSA 1.0.9, "software" sound card definitions redefine
# "default" to do mixing, meaning this device is identical to "default" for
# "software" sound cards.

The problem is I cant get audio from L/R line-out.
Granted if i delete terminal in and delete .asoundrc, reboot, then change setting in XBMC audio hardware i do get L/R audio,
But then to go back to HDMI i need to Create a new .asoundrc, reboot, then change setting in XBMC audio hardware to get HDMI to work again.

( Thanks to vikjon0 ) for this, but it's very time consuming and not easy unless you have tty...


I have a Shuttle/PC with Ubuntu & XBMC installed on it and i can get both spdif and L/R to work at the same time just by changing XBMC to "Analog" obviously when I click "Digital" only the spdif works.

I was hoping someone out there might have a good solution to this problem.
I been trying to get this to work for about 2 weeks with no luck.

Thanks again for any and all help!

If any one knows how to properly setup "asound.conf" for both Analog and Hdmi, any help here would be appreciated.

Thanks again.

I use this a .asoundrc in .xbmc user dir
pcm.!default {
type plug
slave {
pcm "both"
}
}

pcm.both {
type route
slave {
pcm multi
channels 4
}
ttable.0.0 1.0
ttable.1.1 1.0
ttable.0.2 1.0
ttable.1.3 1.0
}

pcm.multi {
type multi
slaves.a {
pcm "tv"
channels 2
}
slaves.b {
pcm "receiver"
channels 2
}
bindings.0.slave a
bindings.0.channel 0
bindings.1.slave a
bindings.1.channel 1
bindings.2.slave b
bindings.2.channel 0
bindings.3.slave b
bindings.3.channel 1
}

pcm.tv {
type hw
card 0
device 3
channels 2
}

pcm.receiver {
type hw
card 0
device 0
channels 2
}

Then configure xbmc with
digitaal on
ac3 off
dts on
both
hdmi
downmix on

Hopefully it works for you

No this does not work. At least not for me.
Yes, this will get both the HDMI and the S/PDIF connectors working, but not the analog audio jack as requested by the orginal poster.

In order to also get the analoge audio jack working you need to create a .asoundrc file like this:

Code:

pcm.!default {
type plug
slave {
pcm "both"
}
}

pcm.both {
type route
slave {
pcm multi
channels 6
}
ttable.0.0 1.0
ttable.1.1 1.0
ttable.0.2 1.0
ttable.1.3 1.0
ttable.0.4 1.0
ttable.1.5 1.0
}

pcm.multi {
type multi
slaves.a {
pcm "tv"
channels 2
}
slaves.b {
pcm "receiver"
channels 2
}
slaves.c {
pcm "analog"
channels 2
}
bindings.0.slave a
bindings.0.channel 0
bindings.1.slave a
bindings.1.channel 1
bindings.2.slave b
bindings.2.channel 0
bindings.3.slave b
bindings.3.channel 1
bindings.4.slave c
bindings.4.channel 0
bindings.5.slave c
bindings.5.channel 1
}

pcm.tv {
type hw
card 0
device 3
channels 2
}

pcm.receiver {
type hw
card 0
device 1
channels 2
}

pcm.analog {
type hw
card 0
device 0
channels 2
}

Please bear over with the obviously misleading naming convention used in this file...

This configuration works for me on the ASRock 330.

In Settings->System->Audio HW
audio=analoge
downmix multichannel audio to stereo = yes
Audio output device: PLUG:BOTH

Now you should be able to get audio out of the analog audio jack....

Cheers,
Lars

Lars,

Sorry it took me so long to respond i was out of town for a few days.
I did however replace my .asoundrc with the one you have listed above and changed:

Audio=Analog
Audio Output Device to: "plug:both"
Downmix Multichannel Audio to Stereo = Yes

THANK YOU this did get audio to both HDMI and analog L/R.

One problem that i have, which is above my head is the Music crossover. When it goes to fade in the next song i get:
Failed to initialize auto hardware

I see this problem addressed here:
http://forum.xbmc.org/showpost.php?p=396...tcount=141
but this will not work with Line-out L/R

Thanks again,
Nathan

[nathan909]

Just checking in to see if anyone has found a fix for this.

[jbernardo]

On my brand new pointofview mobii sidney-II, I used your asound.conf but had to set the sound to digital, with output plug:both and pass-through hdmi. And now I have sound through the analog audio jack as well as through hdmi.
Thanks!

[nathan909]

jbernardo, Did you get mp3 crossover to work?

[jbernardo]

Just to clarify we're speaking the same language (I come from a electronics background before IT, so for me crossover is a filter), you mean the crossfade from one song to another, when one ends and you mix it with the beginning of the next? Or something completely different?

[nathan909]

jbernardo,

Yes i was referring to the XBMC feature:
Settings>Music>Player>Crossfade Album Tracks>ON

With this setting on, it will not play every other song.

With mu other asoundrc in 1st post it does, buther there is no anolog out.

Thanks again!!!

[jbernardo]

Ok, I'll check it tomorrow - the kids are watching their shows now, and later the wife will want to watch hers...

[jbernardo]

Crossfade is broken here too. I get "audio device unavailable" if I have crossfade enabled, with it disabled sound keeps working when I change tracks.

I am experiencing the same problem, with a regular PC (no atom), ubuntu 9.04 32 bits.

I've opened a bug ticket:

http://trac.xbmc.org/ticket/7628

If you can attach your debug logs there that would help

[htpcero]

Folks if you are still having this problem, you may want to look at this bug discussion for a hint on the possible solution (at least it worked for me)...

[nathan909]

Im not sure if i follow this. Where would i make the changes? And will the changes break the HDMI audio out for the ASROCK?

Thanks again
