Bug Description
Binary package hint: linux-image-
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-
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.
Thank you for taking the time to report this bug and helping to make Ubuntu better. You reported this bug a while ago and there hasn't been any activity in it recently. We were wondering is this still an issue for you? Can you try with latest updates or the Ubuntu release? Thanks in advance.
