AVI audio playback problems

[toison]

Hi,
Wondering if anyone could help me. A new user of "Gloria", I just bought a pair of Logitech V20 speakers for the Toschiba Satellite Laptop, Just hovering over a FLAC file with the mouse and playback starts on the speakers. So far, so good.
However, when I open a AVI file with mplayer, the audio will only come out the internal speakers not out the V20s.
Is there a series of settings I might have missed ?

Two things you can check regardless of the Hardware--

1. Take a good close look at where you are plugged in,it is the right hole ?
I was recently 'stumped' until i discovered I'd plugged into the microphone socket!

2. Is the jack plug pushed right in ?

Theoretically if you have sound from the speakers it should be redirected to the 'phones when you plug them in,the 'phones normally interrupt the supply to the speakers.

As hovering the mouse over a FLAC file (Rythmbox ?) produces sound in the speakers but no sound comes out while using Gnome Mplayer to play an AVI movie, I am inclined to look at this from a software issue instead of a hardware issue.

Here are my settings (I've tried others but to no avail):

Multimedia Systems selector
Audio default output plugin: Autodetect

Sound preferences: everything at Autodetect except for device = Logitech USB speaker (ALSA mixer)

Gnome Mplayer Preferences Audio output = alsa

@ eddie:

Thanks for your reply. It could have well been the case but I double checked and everything is plugged-in ok.

V20 portable speakers (USB powered)

??
If the speakers really are powered by USB why even bother - you get at most 2.5 W (5 V @ 500 mA)
(You don't get decent sound until you have at least soem10 "real" watts)
Hardly better sound than internal speakers
Check the settings in the programs you use
The preview (or better "prehear") is handled separately from the players
Also set sound sink to USB
You did not mention that it was USB speakers at first. One of the mysteries I don't really get to grips with is why USB sound works flawlessly for the most part but creates problems in some cases
I'll add this to my list and come back to you

Thank you for your reply Husse.

- Yes they are powered by USB. And the volume is about 10 times as loud as the internal speakers. They were bought for portability.

Hardly better sound than internal speakers

Do not take my word for it but (http://reviews.cnet.com/pc-speakers/log ... mncol;rnav) these are part of a very mobile setup for my wife to carry to her classes which are never at the same place (she never knows beforehand the size of the room).

Check the settings in the programs you use

I would prefer to use Gnome Mplayer for all of its features set. But, as I am stuck right now, I am willing to try anything out.

The preview (or better "prehear") is handled separately from the players

Thanks for the insight. Since the "prehear" works, will it not be better to look for a solution to my settings from that perspective ? And then where to look ?

Also set sound sink to USB

We'll do.

mplayer has long needed some configuring as the default values are less than optimal
