Lost all audio after updating (Ubuntu netbook remix)
 
I have just bought a Toshiba NB100-11R. It worked out of the box, including audio.
I ran Update manager and installed 150 updates everything that it gave me.
Now I have lost audio completely.

Typical messages I get are:

When trying to play a mp3
Failed to connect stream: Invalid argument

Changing volume
No volume control GStreamer plugins and/or devices found.

Testing devices
audiotestsrc wave=sine freq=512 ! audioconvert ! audioresample ! gconfaudiosink profile=music: Failed to connect stream: Invalid argument


I am completely new to Linux and apart from finding where the terminal is I know nothing about it.

I have seen similar problems on various forums but I quickly got lost in the techy responses.
Apart from taking netbook and recovery disc to a PC repair shop do you have any suggestions?

Thanks

hi

I do not like ubuntu styles but do not give up yet.

There are 3 issues....one the update may not have updated correctly and you have a broken update

2) the update no longer uses a certain backend...and you are trying to use it

3) you have not named your music player but I do not like seeing streaming message when you are trying to play a local file?

------------------

some suggestions

do not take it to a store....they are unlikely to help as they tend to be ms users

instead...download a live cd.....slitaz is ideal for netbooks and see if it can play the file on your hard drive

or instead ...install vlc and see if that can play your file

check that your mixer levels are good...unmute pcm...master...volumes...and slide controls up
run alsamixer to check or alsamixergui....or name the mixer control on your pc pls


-----------------------
troubleshooting sound where a kernel and or alsa package has stuffed your pc is a little tricky but lets try for simple solutions first eh?

Have you restarted the system since you applied the updates ? I've noticed audio sometimes breaks after an update to the audio components.

I typically run alsaconf and let it reload all the sound modules to get it working properly again, but for some reason I'm thinking Ubuntu removed alsaconf from their modified version of Debian.

Maybe try sudo alsa force-reload

It's fixed
 
Many thanks for the amazingly quick replies.

Using the links suggested I worked out that there was a sound kernel problem (I think) which led me to a google search which found a fix for the bug. Apparently every NB100 user loses sound when carrying out the normal update - well done Toshiba.
The fix is at https://bugs.launchpad.net/netbook-remix/+bug/298607.

I am well impressed by the Linux community even if I don't understand Linux.

Thanks again.

Glad to hear you were able to find a fix, even if we weren't able to point you directly at it.

Stick around theres lots of community working around here to help each other. :)

yes now that the OP is fixed....the link posted includes a message from a newbie...that they rebooted at each stage. heh heh. (me thinks a ms user)

There are legit reasons for modifying system files that need a reboot....they include installing a new kernel, modding the gfxmenu for grub legacy, modding the grub2 graphics. Most other system files, can have their services restarted with a command eg
/etc/init.d/alsa-utils restart

Hi,

Sorry for the bump on old thread but just wanted to let anyone else know that has this problem that the sudo alsa force-reload-command solved a nasty problem for me when after a update all my audio-hardware weren't showing up in audio preferences.

It took me a couple of hours googling to come up with this solution so this might boost it a bit :)
