Hasty reply. In further use, didn't always work. I removed the PCI
sound card, removed the plastic cover from the sockets on the system
board and connected speakers. Subsequently commands such as this
always work.
set AUDIODEV=plughw:CARD=ICH5,DEV=0 ; play a42.WAV
SPECULATION
The PCI card was meant to give better quality sound and was operated
properly by the Windows system present when the machine was sold by
Dell. When multiple sound devices exist, Linux still doesn't identify
devices properly.
REVISED CONCLUSION
Upstream documentation relating to sound hardware and software needs
attention. Software also needs debugging.
