Hello Takashi,
Here is a tested patch for Audiotrak Prodigy 192:
Fixes: -------- * correct card specific ice1724 initialization * working IEC958 output of the card * renamed capture controls
New features: ------------------ * analog input switch (line-in/mic) * optional ak4114 based MI/ODI/O card detection & support: IEC958 input, digital input switch (toslink/coax)
Unresolved issues ----------------------- * Analog and digital input enums are listed on playback panel of alsamixer, I do not know how to push them onto the capture one.
