the emu10k1 has three different capture pcm devices: from ac97, mic and fx. well, callint as "ac97" is not exactly correct. but anyway,the "standard" capture pcm refers to the first one. on emu10k1, the signals from ac97 are routed to the capture fifo and then you can record them. in addition, you can route other sources and mix them to this capture fifo. the switch shown above does this. if these switches are on, then the signals from livedrive are routed and mixed with the signals from ac97 (if enabled). there are another switches, "Line LiveDrive Playback Volume". this will route the input of livedrive to the DAC, i.e. you'll hear the sounds from front speakers. i guess, these switches are still turned on, in your case.
