Ok I found a workaround. It's not a fix but I can work with apps at least. I checked "defaults-ng.vxml" on the server and compared it to what I had on my local machine. Both had the same value for input mode:
<property name="inputmodes" value="dtmf"/>
However, my local version was missing some config options as follows:
<property name="audiofetchhint" value="prefetch"/>
<property name="audiomaxage" value="300"/>
<property name="audiomaxstale" value="0"/>
<property name="datafetchhint" value="prefetch"/>
<property name="datamaxage" value="300"/>
<property name="datamaxstale" value="0"/>
<property name="documentfetchhint" value="prefetch"/>
<property name="documentmaxage" value="300"/>
<property name="documentmaxstale" value="0"/>
<property name="grammarfetchhint" value="prefetch"/>
<property name="grammarmaxage" value="300"/>
<property name="grammarmaxstale" value="0"/>
<property name="objectfetchhint" value="prefetch"/>
<property name="objectmaxage" value="300"/>
<property name="objectmaxstale" value="0"/>
<property name="scriptfetchhint" value="prefetch"/>
<property name="scriptmaxage" value="300"/>
<property name="scriptmaxstale" value="0"/>
Once I copied these into the local version then prompts that had "Immediate Playback" attribute set to false were played but ones set to true still gave the same old "ASR Resource"error. Here's the same prompt that I have been showing with the value set to false:

Notice that it doesn't even mention INPUT MODE this time. I'm happy that I can debug now but if anything I'm even more confused and it will add more work as our apps are a mix of true and false for that value. Why will it play when "Immediate Playback" is set to false and not when its true?
EDIT: There was a mix up with where our defaults-ng was stored. The one I posted was being overridden by another one on the MCP. Sorry for insisting the problem was with Composer. The problem is fixed now. Still don't get why the Immediate Playback workaround works though.
