    Unhappy USB soundcard - volume problem

    Hi, I have USB soundcard C-media 7.1 (image) and I have a problem with instalation on Asus WL-500gP. Good instructions are on this page, but for OpenWrt I can't install packages, which I need (ipkg install kmod-sound-core sox kmod-alsa alsa-utils) - they aren't in Oleg repository. I have install MPD, MPC and Esound. Soundcard play music, but volume is not working. Can anybody help me? Thanks and sorry for my English.

    Here is my mpd.conf:
    Code:
    port "6600"
    music_directory "/opt/Hudba"
    playlist_directory "/opt/Mpd/Playlisty"
    db_file "/opt/Mpd/mpddb"
    log_file "/opt/Mpd/mpd.log"
    error_file "/opt/Mpd/errors.log"
    state_file "/opt/Mpd/state"
    audio_output       {
                type    "oss"
                driver  "esd"
                name    "C-Media"
                device  "/dev/sound/dsp"
                format  "48000:16:2"
        }

    try to uncomment/add these lines:
    Code:
    mixer_type                     "oss"
    mixer_device                   "/dev/mixer" #Maybe /dev/sound/mixer ?!
    mixer_control                  "PCM"
    what client are you using?

    About those packages: kmod-sound-core sox kmod-alsa alsa-utils
    They dont exist in oleg but arent needed as well as long as you dont need alsa features.

    I try your instructions. Music play, but volume doesn't work. I use sound client MPC.

    MPD log:
    Code:
    Dec 24 10:51 : avahi: Failed to create client: Daemon not running
    Dec 24 10:51 : Unable to open oss mixer "/dev/mixer"
    Directory sound (/dev/sound/) include: dsp, mixer, mixer1

    Volume is already working! I used:
    Code:
    mixer_type                      "software"
    Exist any equalizer for MPC?
