Is it possible to stop a music MP3 playing? I've got a section of my map where if the player goes very quickly, they'll trigger the next track before the previous one has ended. Ideally, I'd fade the old one out and start the new one, but that doesn't appear to work - instead I get both playing simultaneously. Any ideas? --[[User:Cargo Cult|Cargo Cult]] 14:58, 29 Aug 2005 (PDT)
: Found that the ''stopsound'' command does the trick, in a rather hacky manner - it stops ''everything'' playing. I've got a [[point_clientcommand]] to do this - a [[logic_relay]] timer counts down so that if the first music track finishes playing naturally, it disables the [[logic_relay]] thingy which would send the ''stopsound'' command. If that makes sense. The second, command-sending logic thingy also starts up the relevant soundscape and ambient sounds... --[[User:Cargo Cult|Cargo Cult]] 13:46, 30 Aug 2005 (PDT)
::I know it's most likely too late, but wouldn't it be easier to just kill the entity? --[[User:Vaarscha|Vaarscha]] 14:22, 19 Mar 2006 (PST)
:::FadeIn and FadeOut are in as of Episode One. --[[user:TomEdwards|TomEdwards]] 12:29, 5 Aug 2006 (PDT)
::My hacky way of stopping a sound - set the Volume to 0. Works like a charm. --'''[[User:Campaignjunkie|Campaignjunkie]]''' <sup>([[User talk:Campaignjunkie|talk]])</sup> 21:32, 10 Sep 2006 (PDT)
::NONE of this seems to work for me. I even tried manually doing it using the ent_fire command. --[[User:Darthkillyou|Darthkillyou]] 19:11, 19 Apr 2007 (PDT)

==Definition List==
I've converted this article to use the Wiki's DL system, which simplifies markup considerably. There are a few minor problems:

*The table breaks the list into three due to a Wiki limitation
*Another Wiki limitation means that the Flags had to have their semicolons replaced with dashes
*I couldn't convert the [[Template:I Targetname]], as that would have messed up other articles

Nothing too major. What do people think? With some find/replacing (perhaps even at Valve's end) the conversion could be fairly quick. --[[user:TomEdwards|TomEdwards]] 12:29, 5 Aug 2006 (PDT)

:Personally I think it's a bit much to save a few bytes of bandwidth as I am happy with the current template&mdash;'''[[User:Ts2do|ts2do]]''' 12:42, 5 Aug 2006 (PDT)

:In terms of reading the pages, I see no significant positives or negatives. In terms of editing the pages, I can see that it's simpler and easier to visually parse. However, the Input/Output/Flag listings are basically "finished" (in that I can't imagine any significant improvements in information ''content'' that could be made), excepting new entities.
:Given that, (and given that the <code><nowiki>'''</nowiki></code>s straddle the word and so would require regular expressions to change automatically, instead of just simple find/replace?), I can't see the change being worthwhile in cost:benefit terms. But if you want to volunteer ... --[[User:Giles|Giles]] 12:55, 5 Aug 2006 (PDT)
::You could catch them with the <nowiki>*'''</nowiki> pattern, but honestly I have no idea about regular expressions. --[[user:TomEdwards|TomEdwards]] 13:06, 5 Aug 2006 (PDT)

==SourceEntityName==

In a map I'm currently working on, I need to play a sound and it must follow the object that is supposed to make this sound. After realizing that there's no "parent" property for this entity I tried to use the "SourceEntityName" one. Actually it works well in the way that the sound is following the object, but the problem is that the sound's volume has been lowered and can't be heard at all. You must put the player 30 units away from the ambient_generic to hear it properly. It's really strange because it's volume is set to 10 (the maximum) and if I delete the "SourceEntityName" field, the sound's volume reverts to normal.. Is there a way to have a sound following a moving entity without having to duplicate it 10 times in order to multiply the volume by 10 ? --[[User:NykO18|NykO18]]
:The only way i can think of is making the sound itself louder.

=== Templates ===
I have another problem: When I spawn a prop_physics via point_template and env_entity_maker, Source Entity Name set to the Template. But the Sound is only played where the Template is, even when I use the name fixup (also tried <entityname>&0000-&0002 for Source Entity Name). When the Template is removed, the ambient_generic plays the Sound where the ambient_generic is. [[User:Puchi|Puchi]] 12:11, 4 Dec 2007 (PST)

I made a disco room with multiple func_walls named "speakers" to which I had an ambient_generic with the SourceEntityName set to the speakers. The outcome was only one of the func_walls had music coming from it and it was very low. I tried the same but instead of func_walls I used ambient_generics and this did not work. It seems this does option does not work properly. I was able to get what I wanted by adding more ambient_generics with the same name and same sound file playing at the same time. --[[User:MongoTheMad|MongoTheMad]] 17:08, 22 July 2009 (UTC)
: Seems to me that you should try to find the name of the entity that's actually spawned. Try turning on developer mode and +using it: the name should appear in the console. --[[user:TomEdwards|TomEdwards]] 17:22, 22 July 2009 (UTC)

==Starting Silent==
I've noticed that you cannot get this entity to actually start on map spawn - not automatically, on its own - making the ''Start Silent'' flag a mystery. ...or am I wrong? I can't hear anything at least. Can you? --[[User:Andreasen|Andreasen]] 18:32, 10 Sep 2006 (PDT)

:In theory, having this flag off starts the sound automatically only if it's a looping sound.  If this is not what you observe, (complete guess:) the problem may be because it is trying to start the sound before the player is in the map.&mdash;'''[[User:Ts2do|ts2do]]''' 19:36, 10 Sep 2006 (PDT)
::I always thought it was to make the sound fade in rather than start playing at 100% immediately. --[[user:TomEdwards|TomEdwards]] 02:13, 11 Sep 2006 (PDT)
:::If it is, you might want to go through the trouble of retesting the functions of the ''PlaySound'', ''StopSound'' and ''Volume'' I/O, because I think those sounds were started silently when I tested them. --[[User:Andreasen|Andreasen]] 09:42, 11 Sep 2006 (PDT)
::::Researched it: The ''Is NOT Looped'' flag will cancel out the cleared ''Start Silent'' flag. Whether the sample itself is looped or not, you must always have the ''Is NOT Looped'' flag cleared for it to play at the beginning. --[[User:Andreasen|Andreasen]] 12:05, 11 Sep 2006 (PDT)

Which is sorta exactly what I said&mdash;'''[[User:Ts2do|ts2do]]''' 13:46, 11 Sep 2006 (PDT)
:Yes, but now I've confirmed it too. :P ("In theory" sounded so vague.) --[[User:Andreasen|Andreasen]] 14:13, 11 Sep 2006 (PDT)

==Needs clarifications==
Descriptions like "<integer> Spin up time (0-100)" mean ''nothing''. This page needs actual descriptions of what the different values do. [[User:Thelonesoldier|Thelonesoldier]] 00:10, 5 Feb 2007 (PST)

Many of the entity descriptions on support pages are like this I had hoped this place would build up real descriptions to clarify more. This has been an ongoing problem since HL1 [[User:SantagausS|SantagausS]] 21:42, 16 Feb 2007 (PST)

==Sounds not working on dedicated servers==
I have noticed that sound scripts do not seem to work on dedicated servers only raw sounds will work? This happens in hl2dm on linux servers. Can anyone confirm this and if so I think I will add a note as it caused me to lose quite a bit of time screwing with it. [[User:SantagausS|SantagausS]] 21:42, 16 Feb 2007 (PST)
:This is something to do with server and client soundscripts being different, IIRC. Most script sounds ought to work, unless you're doing them custom and not shipping your script along with the map. --[[user:TomEdwards|TomEdwards]] 03:21, 17 Feb 2007 (PST)

==Music Previews==
Um... How do you preview music? I can preview .wav sounds but not any of the .mp3 (music) sounds. I hate having to go
in-game to figure out how each music file sounds like. --[[User:Darthkillyou|Darthkillyou]] 18:49, 19 Apr 2007 (PDT)

== Using ambient_generic (or any other means) to create a global ticking sound in Portal ==

I have a func_button with "Use Activates", to start a logic_relay to open a door, play a sound, and activate a timer_relay, of which drives an ambient_generic that plays the Portal ticking noise every second.

The ambient_generic is set with all three flags checked... but the sound still acts as if the "Play Everywhere" flag was not checked.  What gives?  And how else could I make the desired effect?--[[User:volt|volt]] 02:33, 22 Nov 2007 (PST)

Instead use a [[logic_choreographed_scene]].--[[User:MrTwoVideoCards|Gear]] 04:02, 22 Nov 2007 (PST)

== How to use the FadeIn input ==

Does someone ever managed to use this input ? I'd like to start a sound by rising its volume slowly, but it seems there's no way do to so. I tried almost everything, a WAV, a looping WAV, a MP3, FadeIn alone, PlaySound then FadeIn, Volume then FadeIn, PlaySound then Volume and FadeIn. Nothing works, the sound does not start or starts immediately. Surprisingly, the FadeOut input works like a charm.. --[[User:NykO18|NykO18]] 14:49, 1 Mar 2008 (PST)
:You're right, it's broken. The "Fade in time" keyvalue still works, at least. I've looked at the source code and it appears that fadein doesn't work because the sound has to be playing to fade in - and if you start it at full volume, there's no fading to do! I'll look into a fix, but there's all sorts of low-level maths in this code (sound.cpp ln601)... --[[user:TomEdwards|TomEdwards]] 00:47, 2 Mar 2008 (PST)
::I'm out of ideas. --[[user:TomEdwards|TomEdwards]] 01:23, 2 Mar 2008 (PST)
:::Can't you try setting Volume at 0, starting the sound with FadeIn, and then setting Volume at the desired amount? [[User:Solokiller|Solokiller]] 04:11, 2 Mar 2008 (PST)
::::That's what I tried! --[[user:TomEdwards|TomEdwards]] 05:12, 2 Mar 2008 (PST)

== Sound sample rate ==

Hi there everyone, I was compressing a song to crappy sample rate, to give it the impression it was being played on a radio. It seems like the lowest bit rate (I think) .wav files support is 8KHz, (or apparently 8,000 something), so I chose that. But when I try to play the audio ingame, it says it's sample rate is not supported! So I'm just wondering if someone can clarify to me the supported range of sample rates.
:44KHz and nothing else AFAIK. --[[user:TomEdwards|TomEdwards]] 15:36, 3 August 2009 (UTC)

::What a range that is :P If anyone else would like to add, please do.--[[User:Tgp1994|Tgp1994]] 15:44, 3 August 2009 (UTC)

== Lotsa bugs ==

Doesn't anyone think Valve should be doing something about all of these {{bug|s}}?
