Public bug reported:
Binary package hint: linux-image-2.6.15-23-386
HARDWARE -
Tyan mother board
Pentium PIII, 750 CPU
Creative Labs SoundBlaster Live! (driver - emu10k1)
PROBLEM - (Symptoms positive and negative)
Sound not operating.
Alsa mixer and Gnome mixer both reporting that there is no sound device installed.
No modules apparently installed.
SOLUTION -
Went to the Alsa web site, found my particular sound card, downloaded 3 packages and followed the directions on the page INCLUDING running ./snddevices. ReBoot. Sound now operating.
CONCLUSION -
The Ubuntu alsa packages, when installed, are not completing the operation of installing the sound devices (/dev/dsp /dev/mixer /dev/sequencer /dev/midi). This is fatal to the operation of sound on a GNU/Linux system. This is a particularly obnoxious problem considering that the sound was operating prior to the upgrade to this particular kernel (this also occurred on a clean install on a separate partition). Which particular package was responsible for the lack of sound devices I have no way of determining. However, since ./snddevices would not operate/could not be found until AFTER I had done ./compile ./make ./make install on the three packages, I have to conclude that something in the packages that Synaptic offered was lacking the appropriate programs/functions.
TO REPRODUCE -
On the above hardware, update to linux-image-2.6.15-23-386. Sound that had been working satisfactorily PRIOR TO update suddenly no longer exists.
COMMENT -
This is the second time that an updated image has destroyed the sound on my computer. I would have thought that, after the first time, it would have been fixed.
** Affects: linux-source-2.6.15 (Ubuntu)
Importance: Untriaged
