When I turn my laptop this afternoon, I suddenly lost my sound and got this ugly red cross beside my speaker.
When I double click the icon, I got this message.
Then I open System > Preferences > Sound ……I lost my sound device.
I can’t run ‘alsamixer’ from the terminal, then I did log off and reboot the system …..
nothing to make the sound work.
The last thing I did was I regularly update my system using:
taufanlubis@toshiba:~$ sudo apt-get update
taufanlubis@toshiba:~$ sudo apt-get upgrade
taufanlubis@toshiba:~$ sudo apt-get dist-upgrade
It’s normal daily routine that I do every day and I always use the ‘main server’ for my repository, so I’m very sure that it didn’t cause the problem.
When I googled, I found a solution in here. This blog belongs to Kamil.
http://linux.dsplabs.com.au/no-volume-control-gstreamer-plugins-and-or-devices-found-no-sound-or-voume-control-bug-on-ubuntu-p31/
He mentioned that it could probably a a Gnome bug and is most likely distribution independent. I agree that it may caused by independent distribution. When you install something using Sypnatic Package Manager, any programs that have been tested by Ubuntu Team and compatible with it has a Ubuntu logo beside the package title.
Because, there’s so many applications that I’ve run in my laptop.
But, who cares….. If you wanna try a new thing then you have to be ready with consequences.
The point is how we can fix the problem. So, here it is.
Problem 1. I don’t have any more access to my audio.
taufanlubis@toshiba:~$ ls -l /dev/snd
total 0
crw——- 1 root audio 116, 3 2007-12-20 12:51 seq
crw——- 1 root audio 116, 2 2007-12-20 12:51 timer
taufanlubis@toshiba:~$
If you see the list in my /dev/snd directory, the access is only for root. Then I gave a new access to me (taufanlubis).
taufanlubis@toshiba:~$ sudo chmod -R a+rwx /dev/snd
for temporary access. But, I got a new error message.
Then I try to make it permanent.
taufanlubis@toshiba:~$ sudo adduser taufanlubis audio
The user `taufanlubis’ is already a member of `audio’.
Strange, now I’m part of the groups but I still can’t hear the sound.
I though it’s caused by Gstreamer plugins.
So, I did update my system again ….
taufanlubis@toshiba:~$ sudo apt-get update
taufanlubis@toshiba:~$ sudo apt-get upgrade
taufanlubis@toshiba:~$ sudo apt-get dist-upgrade
…. and restart my laptop again.
Problem 2. I lost my sound device.
But, still there is no sound.
Then, I just realized that I don’t have my /dev/dsp, /dev/mixer, /dev/snd/pcm* anymore.
That’s why, I can’t run alsamixer from my terminal.
So, re-install my sound driver. Now, I got my device back.
taufanlubis@toshiba:~$ ls -l /dev/snd

taufanlubis@toshiba:~$
taufanlubis@toshiba:~$ ls -l /dev/dsp
crw——- 1 root audio 14, 3 2007-12-20 19:40 /dev/dsp
taufanlubis@toshiba:~$ ls -l /dev/mixer
crw——- 1 root audio 14, 0 2007-12-20 19:40 /dev/mixer
taufanlubis@toshiba:~$
Problem 3. I lost my access to System > Administration > Users and Groups.
I don’t know how but I don’t have any access to ‘Users and Groups’ which is bad because I can’t set the permission to my user login (taufanlubis).
The only way is I have to run it as ‘root‘. So, I opened my terminal, Application > Accessories > Terminal, login as root and open ‘users-admin’ application.
Then, I updated my ‘User Privileges’ and reboot the system.
I have my sound back.
Checked again the permission.

Everything is ok.
I have my sound icon back to normal. Test with xmms, …..done….. I can hear the sound again.
package GStreamer-nya perlu di install dulu nggak mas?
kan dibilang nggak ada GStreamer tuh atau dah langsung aktif GStreamer-nya ketika dah install ubuntu 7.10?
Pada saat error Gstreamer muncul, saya coba install ulang ternyata suara tetap tidak keluar dan device-nya tetap tidak muncul.
Tapi setelah saya install ulang driver soundcardnya, ternyata berjalan dengan baik, jadi sebenarnya bukan problem di GStreamer-nya.
maksud mas dengan driver soundcard itu alsa-driver ya?
soalnya saya sudah install alsa-driver dari source-nya 2 kali dan tetap tidak ada suaranya.
dan saya juga telah melakukan intruksi yang mas tulis di atas.
apa ada cara yang lain supaya saya bisa mendapatkan suara di laptop saya lagi.
soalnya ketika saya install opensuse 10.3 soundnya kedetect kok, cuma ubuntu aja yang nggak neh.
mohon di bantu lagi mas.
thanks
PS: laptop saya HP Pavilion tx1000
hello mas taufanlubis, saya mau nanya lagi neh.
saya menerima driver sound dari mas, yang mas kirimkan ke email saya tapi saya mengalami masalah dalam instalasinya.
masalah yang saya alami terjadi ketika saya menginstall alsa-utils, karena ketika proses instalasi muncul pesan unmet dependencies
pesan errornya mengatakan kalau alsa-utils membutuhkan curses library.
yang saya ingin tanyakan adalah curses library ini nama paketnya apa ya?
soalnya saya dah coba cari paketnya di synaptic tapi tidak ketemu.
saya harap mas taufanlubis mau membantu saya lagi?
thanks
