No sound in KUbuntu 14.10, only Dummy output device listed

**fly66** · January 11th, 2015

Fresh and new installation of Kubuntu 14.10. Same problem with some recent live dvd (ubuntu gnome 14.10 and others). This issue is not present with Ubuntu 14.04. My soundcard is Hercules "Game Theater XP 5.1".
Tried this command:

Code:

sudo alsa force-reload

output:

Code:

Unloading ALSA sound driver modules: snd-cs46xx snd-ac97-codec snd-pcm snd-seq-midi snd-seq-midi-event snd-rawmidi snd-seq snd-seq-device snd-timer.
Loading ALSA sound driver modules: snd-cs46xx snd-ac97-codec snd-pcm snd-seq-midi snd-seq-midi-event snd-rawmidi snd-seq snd-seq-device snd-timer.

So it seems ok to me.

I tried to uninstall and reinstall with these commands:

Code:

sudo apt-get remove --purge alsa-base pulseaudio

and

Code:

sudo apt-get install alsa-base pulseaudio

This is the output of the second command:

The needed firmware files used to be a part of the kernel, but got moved out for legal reasons in kernel 3.14:
https://github.com/torvalds/linux/co...c207f46cbcae03

This should fix you (reload alsa or reboot when finished):

Code:

cd ~
wget ftp://ftp.alsa-project.org/pub/firmware/alsa-firmware-1.0.28.tar.bz2
tar xjf alsa-firmware-1.0.28.tar.bz2
cd alsa-firmware-1.0.28
./configure
cd cs46xx/
make
sudo make install

could you please break up the commands post #2 as I should type them? somehow it's not working for me

**fly66** · January 11th, 2015

Thanks Temüjin,
first three commands ran fine. Fourth command gave an error because I don't have a compiler installed in my syst

Code:

flavio@PC-Test:~/alsa-firmware-1.0.28$ sudo ./configure
[sudo] password for flavio: 
checking for gcc... no
checking for cc... no
checking for cl.exe... no
configure: error: in `/home/flavio/alsa-firmware-1.0.28':
configure: error: no acceptable C compiler found in $PATH                       
See `config.log' for more details

**Temüjin** · January 11th, 2015

Code:

sudo apt-get install build-essential

EDIT: Actually, you probably don't need a compiler. It looks like the files are already built:

Code:

cd ~/alsa-firmware-1.0.28/cs46xx
sudo mkdir /lib/firmware/cs46xx
sudo cp * /lib/firmware/cs46xx

Hi
I have this problem & am interested in trying installing the firmware, but my sound card is different.
The driver that appears to be being used is reported as snd-hda, so I assume that I wouldnt want to "make" cs46xx firmware. Which one should I use?
TIA
Peter

Your soundcard probably doesn't need proprietary firmware. I suggest you start a new thread and give more information: https://wiki.ubuntu.com/Audio/AlsaInfo

Thanks Temüjin compilation went well.
Now the command make:

Code:

flavio@PC-Test:~/alsa-firmware-1.0.28/cs46xx$ LANG=C make

gives:

Code:

make: Nothing to be done for 'all'.

**Temüjin** · January 12th, 2015

Code:

make: Nothing to be done for 'all'.

That's okay. Just run 'sudo make install'' and be done with it.

**fly66** · January 12th, 2015

Perfect! It works! Now the sound card works like in Ubuntu 14.04: I have problems with audio too loud and with 5.1 output but this is another story.

Thanks for your great support,

Flavio
