Subject: [PATCH] echomixer update 1/4
Date: Sun, 16 Jan 2005 20:01:12 +0100 [thread overview]
Message-ID: <20050116200112.553eef81.pochini@shiny.it> (raw)
- Matrix mixer drawing code cleanup.
- New feature: echomixer can load and restore the status of nominal level
switches.
Tiwai: this is the same patch I posted some days ago, but only the
configure.in patch was merged.
