View Full Version : [ubuntu] 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 :

/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

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 :

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

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.
