I am trying to make a figure span both columns in an acmart document. I have tried using figure* but that simply makes the figure disappear from the document. Here is a sample code:
\documentclass[sigconf]{acmart}
\usepackage{lipsum}
\begin{document}
\title{Title}
\maketitle
\section{Section}
\lipsum[2-4]
\begin{figure}[H]
\centering
\includegraphics[width=\linewidth]{generated_music_example.eps}
\caption{Caption}
\end{figure}
\end{document}
I have also tried using \onecolumn but it puts the figure on a new page on its own (without any text around it despite there being enough space for it).
