    Hi, gentlemen. I'm beginner of FreeBSD.I've installed PCBSD 8.1 on my computer. There's no sound although i 've tried many ways. Could someone kind help me fix it? Because I don't know what had happened.

    1 I've added this code to "loader.conf": snd_hda_enable="YES"

    2 cat /dev/sndstat like this:

    Code:
    FreeBSD Audio Driver (newpcm: 32bit 2009061500/i386)
    Installed devices:
    pcm0: <HDA Sigmatel STAC9228X PCM #0 Analog> (play/rec) default
    pcm1: <HDA Sigmatel STAC9228X PCM #1 Analog> (play/rec)
    pcm2: <HDA Sigmatel STAC9228X PCM #2 Digital> (play)



    3 mixer code:

    Code:
    Mixer vol      is currently set to  77:77
    Mixer pcm      is currently set to 100:100
    Mixer speaker  is currently set to  75:75
    Mixer line     is currently set to   0:0
    Mixer rec      is currently set to  75:75
    Recording source: line


    4 the code in /etc/sysctl.conf:
    Code:
    # Autodetect the most recent sound card. Uncomment for Digital output / USB
    #hw.snd.default_auto=1
    hw.snd.defualt_unit=1


    Thank you in advance.

    Ok. First: [thread=7290]Topics about PC-BSD / FreeNAS / DesktopBSD / m0N0WALL / pfSense[/thread]

    Have a look at the snd_hda(4) man page. The HDA sound chip is used in various different implementations and you may need to tweak which output on your card produces what.
     
    royzhang1234 thanks for this.

    In /boot/loader.conf it should be
    Code:
    snd_hda_load="YES"
    .
    But as you already have several pcm devices, the soundcard is recognized already.
     
    royzhang1234 thanks for this.

    thanks for your replies. I know I should post this problem on the forum of PCBSD, but i've failed to register. Your patience is highly appreciated.

    To Ime@,
    The soundcard is recognized, but there's no sound.

    To SirDice,

    It seems that there's no description to how to tweak output of soundcard.

    best regards!

    The entire man page is dedicated to it!
