For the music player in your s5_responsive.css file look for:
@media screen and (max-width: 1280px){
.ttw-music-player .player-controls {
width:178px !important;}
.ttw-music-player .progress-wrapper {
width:64px !important;}
}
Then just change this to:
.ttw-music-player .player-controls {
width:178px !important;}
.ttw-music-player .progress-wrapper {
width:64px !important;}
And for the accordion, you have a fixed height of 23px on a DIV in your module which is causing this issue:
clear: both; height: 23px;
