Many sound problems on Intrepid ibex

I upgrade two ibex last night and found few sound problems below

First, on video file(mpg,avi ..), when right click and choose >open with >mplayer. will bring up error " [AO_ALSA] Unable to find simple control 'PCM',0 ".
I'm not sure what it is, maybe the config just is not right but I fix this by right click on movie window-> preference then on audio tab, select 'Enable Software Mixer'. [or you can do this by change 'softvol = "no"' to 'softvol = "yes"' in $HOME/.mplayer/gui.conf]

Another sound issue is flash player on web[like youtube] not play sound. /var/log/message said
pnix@pnix-a7n:_NHDT392$ tail -f /var/log/messages

and after run flash, no sound from other application too. I saw bug report for this issue on lunchpad here but no solution for me. I have to kill and restart pulseaudio like this to get sound back.

Fixing sendmail take a long time to start

I notice that my database box[FC6+Oracle10.2] take along time to startup. Sendmail and sm-client very very slow to start[ about 5 minutes ]. There's something wrong in /etc/hosts file. 'newalises' command take long time to update and finish with error below. [root@ora10g ~]# newaliases WARNING: local host name (ora10g) is not qualified; see cf/README: WHO AM I? /etc/aliases: 76 aliases, longest 10 bytes, 765 bytes total [root@ora10g ~]# cat /etc/hosts # Do not remove the following line, or various programs # that require network functionality will fail. 127.0.0.1 localhost.localdomain localhost 192.168.1.55 ora10g [root@ora10g ~]# To fix this, custom hostname[ora10g] need to append to localhost line in /etc/hosts.

using Class.getResource() load resource file in Eclipse

There are many ways to load resource file in java app. What sun recommended is using Class.getResource(" resource_name ") or Class.getResourceAsStream(" resource_name ") then you will get URL and InputStream respectively. If resource_name is specified without "/", it will be prepend with Class package. So resource file must be in same place[folder structure] as the Class. What I love to do is call getResource() with "/" and put resource file at the root of package. This way i can have separate resource folder. below is in Eclipse, 1. From Package explorer right click src folder->click import 2. In import dialog, Choose General->File System ->next 3. from directory:->Browse to your resource folder. 4. to folder:-> I add "resource" as a folder name under src folder. then click "Finish". In the code, load resource with this.getClass().getResource("/resource/buttons1.png") or this.getClass().getResourceAs

Converting dat to mpeg file, to burn vcd on ubuntu

Creating vcd [from dat file] on WinXP, I use "Nero Burning Rom". It can burn dat file to vcd directly. On ubuntu, AFAIK, No burning cd software to burn dat to vcd. I use k3b but it can't burn dat file. It support only mpeg-1 and mpeg-2 format. Dat file need to convert to mpeg first. Thist post will show how I install and use vcdgear to convert dat file to mpeg file. pnix@pnix-a7n:~/progdl$ wget http://www.vcdgear.com/files/vcdgear176-040415_linux.tar.gz --04:21:14-- http://www.vcdgear.com/files/vcdgear176-040415_linux.tar.gz => `vcdgear176-040415_linux.tar.gz' Resolving www.vcdgear.com... 66.98.192.104 Connecting to www.vcdgear.com|66.98.192.104|:80... connected.
