Hi! :-)

I just installed the last TDE stable version, on Devuan ASCII (the
stable version) x64.

Everything seems that went perfect, with one exception:
The only sound option that works is ALSA and its quality is very low.
Any hints?

PS. I understand that the next Devuan version (Beowulf) will be
officially supported.
PS2. Maybe a better option is installing Exe-GNU/Linux.
