    Does OSS support bit perfect? I need to ensure that I can play hi-res audio files (24/96).

    Thanks.

    Solved!!!

    This is what I had to use in the mpd.conf file:

    Code:
    audio_output {
            type            "alsa"
            name            "My ALSA Device"
            device          "iec958:CARD=M2496,DEV=0"
    Now it works under ALSA and I get my bit perfect audio to my DAC.

    [cchhrriiss121212;10569783 I'm not an MPD user, but I think the crash is related to the multiple channels on the ICE1712 cards (it expects to have a single volume control instead of 12 separate ones).

    I've edited the /usr/share/alsa/cards/Ice1712.conf
    like in this bugfix.
    For this you have to open a terminal/konsole and you have to open
    gedit as ROOT.

    > sudo gedit
    (after enter you have to type in your password!!!)

    Than open
    the folder:
    /usr/share/alsa/cards/
    find the file Ice1712.conf drag an drop it into gedit
    find these entry like below and insert theses lines lines
    (without the <---- add this):


    ICE1712.pcm.front.0 {
    @args [ CARD ]
    @args.CARD {
    type string
    }
    type route
    ttable.0.0 1
    ttable.1.1 1
    slave.pcm {
    type hw
    card $CARD
    }
    slave.format S32_LE <---- add this
    slave.channels 10 <---- add this

    }
    Fantastic! I have M-Audio 2496. Alsa 1.024 refused to acknowledge the presence of the Analog Outputs, which were the only ones connected , so I got no sound. Adding those 2 lines to /usr/share/alsa/cards/Ice1712.conf solved it, and on reboot all options were available in the drop down box on system/preferences/sound/hardware.

    I spent ages trying get PulseAudio to load a new analog sink to no avail. I was fooled by using Audacious as a test - under preferences/audio/output Alsa plugin /Plugin Preferences it lists a seperate entry for the card - that would play on Analog Out. I assumed Alsa was working fine but I now assume that Audacious is doing something clever/failsafe with that option.

    As an aside, Both Alsa and PulseAudio are seriously excellent - but conversely the docs are woefully inadequate for a new user

    I had the same problem. After much battling, the only way I managed to get sound from my Benchmark DAC1 HDR was by omitting the "device" parameter in the "audio_output" section.

    MPD says it plays the music at its source resolution: fine. But how can I be sure that ALSA is transferring each resolution unaltered? In fact, when I play a test sound sourced at 24/192 (supplied free by Linn Records), the test comes through with flying colours even through my DAC supports max 24/96 through its USB interface.

    Tks for that...I'm gonna check out those files. Easy ref: http://www.linnrecords.com/linn-down...testfiles.aspx

    Can't answer your question I'm afraid, but to continue the thread subject I can advise anyone that I have since upgraded to Natty and the Alsa/Pulse contained therein worked out of the box - which rather stunned me considering the hours I spent getting everything to (almost) work in Lucid. Of course the ICE1712 outputs were still muted by default requiring an unmute by running Alsamixer from the terminal - still haven't worked out what's that's all about - kinda like buying a car but the engine won't start by default - the solution being on page 126 of the manual.

    How can you prove that ADWIG (Alsa Delivers What It Gets)? I have a setup functionally comparable to yours, it is finally working but, as per my previous append, I would dearly like to prove to myself that all is working as expected and desired.

    Looks like a question for here:

    https://lists.sourceforge.net/lists/listinfo/alsa-user

    or even here if u use Pulse:

    Re: Audiophile 2496 w/ ALSA 1.024 - $50 for the person who helps me with this

    I was struggeling with mpd and digital output (SPDIF) and solved it as follows:

    1) aplay -L
    Code:
    null
        Discard all samples (playback) or generate zero samples (capture)
    pulse
        PulseAudio Sound Server
    default
        Playback/recording through the PulseAudio sound server
    sysdefault:CARD=PCH
        HDA Intel PCH, ALC898 Analog
        Default Audio Device
    front:CARD=PCH,DEV=0
        HDA Intel PCH, ALC898 Analog
        Front speakers
    surround40:CARD=PCH,DEV=0
        HDA Intel PCH, ALC898 Analog
        4.0 Surround output to Front and Rear speakers
    surround41:CARD=PCH,DEV=0
        HDA Intel PCH, ALC898 Analog
        4.1 Surround output to Front, Rear and Subwoofer speakers
    surround50:CARD=PCH,DEV=0
        HDA Intel PCH, ALC898 Analog
        5.0 Surround output to Front, Center and Rear speakers
    surround51:CARD=PCH,DEV=0
        HDA Intel PCH, ALC898 Analog
        5.1 Surround output to Front, Center, Rear and Subwoofer speakers
    surround71:CARD=PCH,DEV=0
        HDA Intel PCH, ALC898 Analog
        7.1 Surround output to Front, Center, Side, Rear and Woofer speakers
    iec958:CARD=PCH,DEV=0
        HDA Intel PCH, ALC898 Digital
        IEC958 (S/PDIF) Digital Audio Output
    hdmi:CARD=PCH,DEV=0
        HDA Intel PCH, HDMI 0
        HDMI Audio Output
    ...
    2) Search for your 'Digital' output (in my case iec958:CARD=PCH,DEV=0)

    3) Update your /etc/mpd.conf with your device specification:
    audio_output {
    type "alsa"
    name "My ALSA Device"
    device "iec958:CARD=PCH,DEV=0" # THIS LINE!
    #device "hw:0,1" # optional
    #format "44100:16:2" # optional
    #mixer_type "hardware" # optional
    #mixer_device "default" # optional
    #mixer_control "PCM" # optional
    #mixer_index "0" # optional
    }

    4) service mpd restart & start playing music
