I do not think MPD uses ALSA as such, it's a network thing, isn't it ? It does use ALSA: it's a music player (controlled via a TCP socket). It can also use OSS or Shout for audio output, but mine is configured to use ALSA. Stefan

[Alsa-user] smartLink WinModem w/alsa driver

2008-12-15 Thread FrankK
Greetings List! My fresh install of openSuse 11.0 has a smartLink winModem driver problem. Yast installed smartlink-softmodem-2.9.10-203.1.i596.rpm and configured my modem as an alsa modem. When I look at the dependencies of the rpm, it uses alsa .so libs, so I think yast has it right. Why alsa
