Subject: patch for dmasound bug
Date: Wed, 2 Jun 1999 13:05:09 -0700 [thread overview]
Message-ID: <19990602130509.A269@gondolin> (raw)
This restores the rate/byteswap to normal after playing a beep
if you for example stop timidity, make a beep, resume, the sound
will be slower than normal (without this patch).
