[Bug 634211] [NEW] /dev/dsp* disappeared after upgrade Lucid=>Maverick

[Launchpad Bug Tracker]

You have been subscribed to a public bug:

After a Lucid=>Maverick upgrade, I have no /dev/dsp devices.

I use a Pinnacle Dazzle DVC100 to get video and audio from an analog source (like old VHS player).
I use mplayer to visualize that and mencoder to capture the video and audio.
In my mplayer or mencoder command lines, I used /dev/dsp2 to get the audio stream.

Since my upgrade, I haven't any /dev/dsp* in my /dev/ directory and so I
don't know how to get this audio stream.

For example, here is the output of my mplayer command :
==================================================
$ mplayer tv:// -tv driver=v4l2:norm=SECAM:audiorate=44100:immediatemode=0:forceaudio:adevice=/dev/dsp2:device=/dev/video0
