Missing Audio Icon – Ubuntu Top Bar

Published by:


Lihat deh gambar dari ubuntuforums.org yang saya sertakan di post ini. Yap. Audio icon nya menghilang. Setelah dengan sukses (tanpa sengaja) saya menghilangkannya. Cuma masalahnya lupa, apa yang saya hilangkan. Ketika saya membutuhkan menaikan volume ketika mendengar lagu, eh bingung icon-nya sudah lenyap.

Dan ternyata solusinya belum ketemu di google. Cuma ngoprek sendiri saja. Caranya, klik kanan di bar tersebut. Lalu pilih Panel.

Disana pilih lah Add new items. Dan pilih Indicator Plugin.


Dan audio icon pun muncul kembali.

but in my case, I had to skip some step, like installed alsa-base, which was giving me the non exist message to me. The removing of the folder pulsa-cookie which was not exist.

The other is fine. They make my notebook sound alive.

firefox (in ubuntu) libavcodec error

Published by:

The error I meant is the message displayed at the top of the firefox, said libavcodec is vulnerable and expired (for some reason). After googling and find the article in http://askubuntu.com/questions/851190/how-to-update-libavcodec-on-ubuntu-14-04, the problem is libavcodec is disabled as default.

Libavcodec is needed to play the streaming in the website. Except for youtube. I still can play youtube with libavcodec disabled. I wonder why.

Anyway the solution is make the libavcodec enable.

Here is how

type about:config in the address bar, enter
click “I accept the risk” search libavcodec
change media.libavcodec.allow-obsolete;false to true
