... For sound, install either  alsa.tcz  OR  OSS.tcz  and be sure to read the  Info  tab in AppBrowser. ...
I see in the app browser search result there are both 
alsa-oss.tcz & also 
alsa.tcz. There is no '
oss.tcz'.
I have no sound in either my laptop or in the desktop (sony VAIO and a Dell Dimension 4700), from within the OS, but I know that the hardware works in other OS's. I tried the 'lsmod | grep snd' command in the Terminal, and there was no output. I am thinking that my installation came without any sound drivers?  
EDIT: After installing alsa.tcz and alsa-modules-5.15.10-tinycore.tcz, I tried the 'lsmod | grep snd' command once more, in the Terminal, and there is now output.
Thanks in advance.
