    Question sound working...but no /dev/audio ??

    Hi All,

    just upgraded to maverick from 10.04 and generally looking good

    One issue is sound related .

    although my sound is working, I no longer have a /dev/audio

    I presume this is as a result of pulseaudio ?

    the command line package I'm trying to use does have -i and -o options to specify another device file although it defaults to /dev/audio

    in /dev/snd I have :

    Code:
    /dev/snd$ ls
    by-path  controlC0  hwC0D3  pcmC0D0c  pcmC0D0p  pcmC0D1p  seq  timer
    welshchap@marconi:/dev/snd$ cd by-path
    welshchap@marconi:/dev/snd/by-path$ ls
    pci-0000:00:14.2
    I presume that I need to specify one of these devices ? (e.g. -i =/dev/pcm****) but how do I find which one please ?

    Alternatively how do I get /dev/audio back please ?

    sound driver from sudo lspci -v is :

    Code:
    00:14.2 Audio device: ATI Technologies Inc SBx00 Azalia (Intel HDA)
        Subsystem: Foxconn International, Inc. Device 0e0c
        Flags: bus master, slow devsel, latency 64, IRQ 16
        Memory at facf4000 (64-bit, non-prefetchable) [size=16K]
        Capabilities: [50] Power Management version 2
        Kernel driver in use: HDA Intel
        Kernel modules: snd-hda-intel
    many thanks in advance

    cheers

    Cool Re: sound working...but no /dev/audio ??

    Yeah. Like TS mentions, it's messy.
    Some apps want /dev/ specification, eg. gtkrecordmyscreen.
    What to symlink where to make it work?

    Indeed this happens. I have the same problem. I want to use vlc to capture video from my webcam and I don't know which device should I use.
