No sound played

I'm having the same problem on GNU/Linux (Ubuntu 12.04). Sound worked before and now it doesn't:

java version "1.7.0_25"
OpenJDK Runtime Environment (IcedTea 2.3.10) (7u25-2.3.10-1ubuntu0.12.04.2)
OpenJDK Server VM (build 23.7-b01, mixed mode)

The sound is working on another computer (Ubuntu 13.04):

java version "1.7.0_25"
OpenJDK Runtime Environment (IcedTea 2.3.10) (7u25-2.3.10-1ubuntu0.13.04.2)
OpenJDK 64-Bit Server VM (build 23.7-b01, mixed mode)

Here is a sample of some of the error messages I'm receiving:

Same here: Win7 HP 64-bit, Java 1.7.0_45-b18.
Before update to 1.7.2 was OK.

This ticket is invalid as it relates to a modified or 3rd party client, server, or launcher.

I've got unmodded Minecraft.

The initialization of the sound enginge is missing. That should look like this:

Please attach the complete output of the development console.

Just to let you know: for me the issue is resolved. In the dev. console of the launcher I find that download job "Resources" failed to execute for the first time I've played MC after applying the 1.7.2. So I've restarted launcher and waited about 30 seconds to resume the download job "resources" (this can be related to busy servers) but after the job was succesfully completed all the sound works fine.

I looked in my Minecraft file and all sounds are there.
