Sound not working with hda_intel / Realtek HD under Ubuntu Dapper
I get no sound while running Ubuntu Dapper on my Toshiba Sattelite L30 notebook. There is sound in Windows XP (dual-boot), and XP identifies the sound card as a Realtek HD one. Linux seems to be using the hda_intel driver. I followed the instructions at http://www.linuxforums.org/forum/lin...my-laptop.html
and got the following output:

Also, in Volume Control (from the right-click menu of the speaker icon) there is 2 devices, HDA ATI SB (Alsa) and Realtek ALC681 (OSS), but in System > Preferences > Sound I can only select HDA ATI SB from the Default Sound Card list.
Thanks in advance for any help.
What version of alsa is being loaded (cat /proc/asound/version)? Try downloading and installing alsa-driver-1.0.14rc1, and install it with "model=toshiba" as a parameter.
Also, could you send the output from "lspci -s 0:14.2 -vn" and "cat /proc/asound/card0/codec*"?
Wait, where do I put model=toshiba? at the end of the configure file? also, after i un-bzipped the package, do i just go ./configure, then make, then sudo make install? it's been a while since i ever tried to install a .tar.bz2, ive been using .debs (and .rpms), and im a bit of a
Ok, now that you've posted your codec output, we now have a little better understanding of what your system is.
First step is to download the alsa-driver-1.0.14rc1.tar.bz2 file.
Next, follow these simple instructions (everything after a # is a comment, everything between <> you need to replace with a path>:
cd <build area of choice> # I use my /home/<user>/tmp for small projects
tar -jxvf alsa-driver-1.0.14rc1.tar.bz2 # this will expand the tarball
cd alsa-driver-1.0.14rc1
./configure --with-debug=detect --with-cards=hda-intel
make
# This will build the drivers. The "--with-debug=detect" will make the drivers output more data to dmesg, and the "--with-cards=hda-intel" limits the build to only Intel HD Audio drivers, speeding up the build process considerably.
The next steps require root access:
pushd /lib/modules/`uname -r`/kernel # the shell will substitute uname -r with the running kernel version
tar -zcvf oldsound.tgz sound/ # make a backup of your current drivers because...
find sound/ -name "snd*" -exec rm -f {} \; # ... this deletes them
popd # back to our build area
make install # newly built drivers are copied to the area we just cleaned
modprobe -r snd-hda-intel # remove any currently running drivers
lsmod|fgrep snd # make sure there isn't anything running. Use rmmod to remove any straglers.
modprobe snd-hda-intel model=toshibs probe_mask=1 # here's where the "model=toshiba" goes.
Test everything. Load alsamixer and see if the controls look right. Play sound. Try recording. If everything works ok, the two options ("model=toshiba" and "probe_mask=1") can be added to /etc/modprobe.conf (or whatever debian uses). Let me know if this works, and I can add your system id to the driver.
Also, the probe_mask will eliminate the hda_codec: invalid dep_range_val 0:7fff
checking for directory with kernel source... /usr/src/linux
checking for directory with kernel build...
checking for kernel linux/version.h... no
The file /usr/src/linux/include/linux/version.h does not exist.
Please install the package with full kernel sources for your distribution
or use --with-kernel=dir option to specify another directory with kernel
sources (default is /usr/src/linux).
I just have a fresh install of Dapper, and, after a bit of googling, I'm guessing that /usr/src/linux is where my kernel sources are, but how do I know if I have full kernel sources?
Also, GrueMaster, whats that Registered Tux # in your sig?
You need to load the kernel-source package for your distribution. That will have the necessary headers you need to build and install the drivers. I'm not a Debian/Ubuntu user, so I would'nt know where to tell you to get it, except from the package management program for your distribution. I believe apt-get is the program manager for those distros.
the solution of the problem is compicated and NO sure - it is no sure in 100% it will work.
I am user of L30-134 / Kubuntu 6.10 - and therefore I known the problem myself:
first - check the version on the bios on Your Toshiba - if te varsion is below 1.9 then please download and nstall the latest version 2.3 - then at least You will have sound on the headphones jack
second - the problem with alsa - till today have no exists good drivers for Toshiba L30 - the one solution is swith off the ALSA and work on OSS (however in this point I should one more time mention - sometimes this solutions work, for other person/computer model it is impossible)
Here You are the procedure:
/etc/modprobe.d/sound
options snd-hda-intel model=uniwill-m31 position_fix=1
alias snd-card-0 snd-hda-intel
alias sound-slot-0 snd-hda-intel
