Internal speaker vs. audio out
« on: 2017.January.07. 12:48:25 »
I am using a SCART output from my Enterprise. This also includes the audio, however the sound of the internal speaker is very loud compared to the sound I get from my TV.
I just noticed that I could turn off the internal speaker using bit 7 in the FIXBIAS register (0x80), so just for fun I compiled a version of my demo "First Contact" with this set.
To me, it sounds better to only have the sound coming from the TV, as the sound of the internal speaker isn't very good.

However, I don't think I have seen any other Enterprise game or program  with the option to turn off the internal speaker. Is it just me who prefers to have internal speaker off?
What do you guys use? Only internal speaker, or do you have audio out hooked up to something as well?

I am considering adding an option to my future programs to disable internal speaker at least.

You can switch off in Basic with SHIFT+F7.
But lot of program which write directly the Fix BIAS register don't keep thee current state, and switch on it :roll:
Then the first hardware hack what the Enterprise owners do: remove the internal speaker, or add a hardware switch to it.

For a software: write BIAS via EXOS variable. If don't possible (need a fast BIAS cahenge) then read the Speaker state at the startup and combine with the BIAS values which are will be used. Adding Speaker option are also good idea.
If I remember right the Eat it Up game and few others have a Speaker option.

One trick: if you connect the audio wires from the Tape output instead the Monitor connector you get a louder sound, and without Tape loading sound.

When I used my EP, i connected rarely to external speaker.
This is a good idea, my conversions also reset b7 on fixbias register if I write it directly :oops: , but I will try to keep in mind to write only 00-1f value to fixbias register.
