hi. any help would be much appreciated.

i have a fresh install of ubuntu studio 7.10 and it will not play any sound. the motherboard sound has been disabled and 64 studio with an older kernel will happily play sound through my creative sound blaster pci card, but UbuStu will not. could anyone help (driver, workaround) me here?

james

ps. thanks in advance

Follow these instructions, particularly the part about the newest version of alsa-driver alsa-lib and alsa-util.

Hi Friend

I just once remove alsa util and base and then restart ,it works.
after that installed my conexant modem and after reboot my sound turned out and doesn't work .finally I find some guide as below but haven't tried yet . if you do .let me know about results . Thanks.

Here's the instructions:
1. uninstall every alsa package if you have any
rpm -qa | grep -i alsa - if it shows nothing skip this step
and then
rpm -evv --nodeps alsa-... for every package

2. go to www.alsa-project.org and download these files :
alsa-driver-1.0.15rc1.tar.bz2
alsa-lib-1.0.15rc1.tar.bz2
.alsa-utils-1.0.15rc1.tar.bz2

Open a terminal and type : su then make a directory called alsa into /usr/local/src. Copy the files to this directory and unpack them (tar xjvf alsa-... for every file).

3. go to this page and download the file patch_sigmatel.c.patch-1.0.15rc1-simple. Copy the patch to /usr/local/src/alsa.

4. type this :
patch alsa-driver-1.0.15rc1/alsa-kernel/pci/hda/patch_sigmatel.c < patch_sigmatel.c.patch-1.0.15rc1-simple.

5. do this:
cd alsa-lib-1.0.15rc1/
./configure && make && make install
cd ../alsa-utils-1.0.15rc1/
./configure && make && make install
cd ../alsa-driver-1.0.15rc1/
./configure && make && make install

If the configure script complains about missing some libraries yum for them and try again.

6. reboot
7. after rebooting volume may be muted so use kmix or some other mixer to enable it.

Hope it works for you. I have a Inspiron 1520 .

i havent had time to look at these links yet, but a quick scan shows them to be promising. thanks people - the help is much appreciated i only wish i could return it!

jamwaffle hope this helps i had the same problems tried everything still would lose my sound turned out that the pci card and onboard sound even when disabled were conflicting so i found asoundconf-gtk in the repos it selects and locks in the default sound device of your choice no more problems. hope it helps

thanks so much. i have reinstalled my 64studio 2 copy - but that advice has convinced me to try with ubuntu again. thanks.

james

ps. if only i could do something in return
