Audio Disappeared; /dev/dsp Missing

Asked by taniste

Ubuntu: Lost audio (apparently as a result of a routine SW upgrade).

Volume control now does 'not find any elements and/or devices to control'.

Daemons /usr/bin/esd and /usr/bin/artsd are not running. Attempt to start artsd manually gives error:

  device /dev/dsp can't be opened (No such file or directory)

'lspci -v | less' lists 2 audio devices:

  Intel Corporation 82801I (ICH9 Family) HD Audio Controller (rev 02)

and

  ATI Technologies Inc RV630/M76 audio device [Radeon HD 2600 Series]

I could not find drivers for download at either manufacturer's website.

How can I re-create /dev/dsp? Any other advice?

Many thanks.

you have no alsa driver version. You can use this to compile alsa 1.0.23 but personally I wouldn't waste your time as hardy desktop support ends next month. You can save yourself a lot of effort by simply installing Lucid, Maverick or Natty (Natty is released next month and is NOT LTS).

http://monespaceperso.org/blog-en/2010/05/02/upgrade-alsa-1-0-23-on-ubuntu-lucid-lynx-10-04/
Shows how it can be compiled but your OS has about 5 weeks worth of support left

The compilation failed by I solved the problem by installing a pre-compiled driver from www.linuxant.com/alsa-driver.

Many thanks for your help!
