Hello, ALSA users! I've recently acquired m-audio revolution 7.1 card, that uses snd-ice1724 driver. I have some issues with it, that I didn't manage to cope with (alsa 1.0.11, kernel 2.6.17): 1. While I can properly adjust the volumes with alsamixer, "alsactl restore" (on boot) only raises the volume in the right channel. Left channel stays silent, until I change the PCM control up-down in alsamixer... 2. The card's specification says, that it's playback format is 24 bit. But playback only works, when I convert audio to 32-bit format (S32_LE). Jack also works in 32-bit "mode". Just how can that be? Is the card's actual resolution 32 bits?? There's one more thing: if I enable hardware monitoring of output ports in JACK, and raise the input signal level beyond maximum amplitude (> 1.0, JACK uses floats), the monitored signal does not get clipped, but is properly displayed. Does that mean, that card supports signal range above 1.0? I thought, that integer PCM signal must get clipped above maximum range (e. g. 65535 for 16-bit)... 3. The card's documentation also says that it's recording rate is 96 kHz, but I can run arecord with just any sample rate up to 192... This is also quite confusing. Does it mean that the input signal gets resampled? I would be extremely grateful for any help provided. I also apologize, if I'm asking lame questions. Thank you. --Artem ------------------------------------------------------------------------- Take Surveys. Earn Cash.
