Will Chocolate have PC speaker sound support? Is that possible to code? This thread shows an instance where it would make a difference.

Sorry to bring this up again, but I had high hopes for this source port. Is there any interest in finding a solution to the problem I brought up?

I did manage to find out a few more things about the issue at hand though:

1. The left shift key is unaffected by this bug; I can retain my speed with the left shift key.

2. The problem isn't specific to any one keyboard. I've tried three of them with all returning the same results.

FWIW, I figured it out by trial and error.
Each byte in the DP lump lasts 1/140 second.
Zero byte is silence, otherwise frequency is approximately 2 ^ (7.463 + value * 0.0408) Hz.

PC speaker support is difficult because nobody has ever figured out the exact format of the PC speaker sound effects (difficult to get all the frequencies right, etc).

I don't know, if this is helpful, please have a look at it:

I'm a bit unclear about your bug, and I'd like to get it fixed if possible. As I understand it, your problem is that if you hold down shift to run, pressing any other key stops you running. Is this correct? So, for example, if you were holding down shift and running around a level, pressing space to open a door while continuing to hold shift will result in you stopping running?

What version of Windows are you using? Also, does the same thing happen in any other ports (PrBoom or Eternity particularly).

Also, to answer your other questions: no, the problem doesn't occur in PrBoom (and I don't have Eternity to test it with that), and I am running Windows XP Professional with SP2.

How's MultiPlayer going? I saw some notes about it somewhere on the wiki.

Sound related: Could it be that there is a small glitch that adds an unwanted Chaingun sound once in a while after that weapon is firing a while?

---

Minimizing: When minimizing Chocolate Doom just keeps playing down there; Doom on the other hand stops, which is a way to pause a demo mid-way in case one is interrupted. I also noted that if Chocolate Doom is windowed and you click the upper left icon on the title bar, the menu opens and Chocolate Doom stops, except for the music (at least with TiMidity.) Shouldn't minimizing also stop the game?

That's just how to write code to control the PC speaker. I actually have quite a bit of experience doing that already (see my PC speaker code for DJGPP). The problem is that we don't know the exact format of Doom's PC speaker sound effect files.

---

---

I checked in the first bits of code for the new multiplayer system but there isn't much yet.

---

---

I haven't noticed anything. What happens exactly?

---

myk said:
Huh, talking about sound code, this may be a more relevant report; go to E2M8 or E3M8... don't the monster sounds all come from the Player's position?

---

---

Another thing, how come -record doesn't do anything? It's ignored, so it's impossible to record demos.

---

fraggle said:
However, this does not apply on level 8: sounds are never cut off. Note that by "level 8" I mean Doom E*M8 and MAP08 of Doom 2/Final Doom as well.

You can test it out by loading up E1M8, waking up all the demons and then clipping through the wall to the far end of the star shaped arena. You can still hear the demons growling from miles away.

I wonder why that is. Why on map08 of Doom2? Was it left in by mistake? Never noticed this one.

---

fraggle said:
Not quite. What you are describing is Doom's normal behaviour.

Normally there is a cut off on sound effects. They get quieter and quieter with distance, then after 1200 units you cant hear anything. However, this does not apply on level 8: sounds are never cut off. Note that by "level 8" I mean Doom E*M8 and MAP08 of Doom 2/Final Doom as well.

I've tested in Windows, and it works for me. "chocolate-doom -record testing" records a demo named "testing.lmp", just like Vanilla Doom.

In Doom this code is likely either modified or augumented somehow by something that didn't make it to the released source, or was disabled and replaced by the boss awaken/die sounds that are heard from anywhere, just like switches.

Sounds get fainter as you move away from monsters in Doom E1M8, E2M8 and E3M8, but they are always equally loud, as if you had the monsters stuck to your ear in the same maps using Chocolate Doom.

If Doom's sound behaves differently in those maps, then it does so in a different way than Chocolate Doom. I did what you proposed in E1M8, and there's an evident difference in the Demons' sound while inside and outside (outside is softer), while in Chocolate Doom its like you have the Demons in your head. It's insane!

Go to E3M8 in Chocolate Doom and awaken the monsters; when they attack it sounds like the marine is shooting the fireballs and stuff.

fraggle said:
The effect is dependent on your sound volume setting. I've tried it on both Vanilla and Chocolate and it seems the same to me. I've been adding to my writeup, you might want to try the "demonstrating the effect" explanation for yourself.

---

fraggle asked a while ago:
Do you have a list of demos which PrBoom does not play back properly? This would be most helpful. Thanks.

---

---

And I replied a bit lazily:
There aren't too many that I can think of - they've done a pretty good job of squishing the main problems. The biggest class of demos that don't work are ones for things like Hacx, where bugs in the dehacked support let Prboom down, and ones where there are map issues, such as (presumably) on hr18. IIRC there was also a full-game coop involving Vince that screwed up on map30. Give me a while and I'll provide a list of a few specific ones.

Here you can find a demo that was recorded with doom2.exe, plays back with it but desyncs with PrBoom or Eternity.

At compet-n: hr18-348, hr18-851, hr182206, hr182425, hr184144, hf184238
i.e. six demos all on the same map. Not every demo on this map desyncs though - all the other compet-n demos on this map that I tested played back OK.

At DSDA: h2322437. This is on the HR2 beta.
