Thank you for your message, Actually the direct path settings you suggested fixed the issue when the songs were not playing completely as I mentioned before.
And for 404 issue
I do NOT have sh404sef plugin nor K2 Component.
I only have following custom redirects in my .htaccess file
RewriteEngine On
RewriteCond %{HTTP_HOST} ^domain.com [NC]
RewriteRule ^(.*)$ http://www.domain.com/$1 [L,R=301]
RewriteCond %{REQUEST_URI} !\.[^./]+$
RewriteCond %{REQUEST_URI} !(.*)/$
RewriteRule ^(.*)$ https://www.domain.com/$1/ [R=301,L]
# Redirect all /index.php/ urls
RewriteRule ^index\.php/(.*)$ https://www.domain.com/$1 [R=301,L]
# Redirect /index.php to root domain
RewriteCond %{THE_REQUEST} ^[A-Z]{3,9}\ /index\.php\ HTTP/
RewriteRule ^index\.php$ https://www.domain.com/$1 [R=301,L]
# Permanent URL redirect
Redirect 301 /component/content/featured https://www.domain.com
Even removing the above code did not fix the issue.
