Re: [linux-audio-user] Audigy2/emu10k1 ALSA JACK audio capture problem

Hi all, This is my first post to the list and I'm still pretty much a newb, so go gently... :-) I have an Audigy2 Platinum Pro ZS card that I would like to use for 6 channel input and output work. I am using JACK (0.99.49) via the QJackCtl (0.2.14) frontend. I've installed ALSA 1.0.8 with Lee's emu10k1 multichannel v0008. I am running a pretty much stock, up to date FC3 distro using kernel 2.6.10 with the realtime-lsm kernel module installed so I have realtime privileges for jackd. /proc/asound/devices: 4: [0- 0]: hardware dependent 9: [0- 1]: raw midi 8: [0- 0]: raw midi 19: [0- 3]: digital audio playback 18: [0- 2]: digital audio playback 26: [0- 2]: digital audio capture 25: [0- 1]: digital audio capture 16: [0- 0]: digital audio playback 24: [0- 0]: digital audio capture 0: [0- 0]: ctl 1: : sequencer 6: [0- 2]: hardware dependent 10: [0- 2]: raw midi 11: [0- 3]: raw midi 33: : timer All software seems to be working properly. My problem is that I cannot figure out how to configure my 6 desired capture channels so that I can read signals on the L & R channels of my 3 Line In inputs. I just think I have a configuration problem Any and all help greatly appreciated. Here is the PCM device definition from my .asoundrc file (which is a modification of the example file found on the included reference webpage): ################################################################################ # # 5.1 Channel Surround Sound # # Reference information: # http://alsa.opensrc.org/index.php?page=SurroundSound ctl.jack51 { type hw card 0 } pcm.jack51 { # "asym" allows for different handling of in/out devices type asym playback.pcm { # # route for mmap workaround type route slave.pcm surround51 # # Had to switch all L and R Channels to conform playback # # channels within JACK to standard 5.1 channel mapping. # # The trailing 1's indicate unity gain (valid values are 0.0-1.0) ttable.0.1 1 # routes 0 to 1 (playback_1 [0] to output channel 1 [1]) ttable.1.0 1 # routes 1 to 0 (playback_2 [1] to output channel 0 [0]) ttable.2.3 1 # routes 2 to 3 (playback_3 [2] to output channel 3 [3]) ttable.3.2 1 # routes 3 to 2 (playback_4 [3] to output channel 2 [2]) ttable.4.5 1 # routes 4 to 5 (playback_5 [4] to output channel 5 [5]) ttable.5.4 1 # routes 5 to 4 (playback_6 [5] to output channel 4 [4]) } capture.pcm { # # 2 channels only type hw card 0 } } ################################################################################ Using this "pcm.jack51" from within QJackCtl (equivalent to. jackd -R -dalsa -d jack51 -S) I get 2 Capture channels (which both appear to contain the R channel of Line In #1) and 6 playback channels (which are correct). BTW, I can use my jack51 PCM from within QJackCtl because I edited the "Interfaces" menu via the qjackctlrc file so that I have a "jack51" menu option. Once JACK is started, channel interconnectivity works correctly. How do I write the "capture.pcm" part of my .asoundrc file so that all 6 inputs become capture channels in JACK? I've done loads of reading on customizing a .asoundrc file and have tried many permutations in attemting to configure my Audigy2's 6 input channels, but no luck so far... There seems to be a good deal of information for configuring ALSA for *playing* audio, but not so much for *capturing* audio! Does anyone have any experience with this that I could draw on and would be willing to help? Other questions: Is this supported for my hardware yet? Any recommendations for multichannel (at least 6 in & out) cards that are currently well supported? Thanks in advance for any assistance. I can post more detailed info as needed. -Rick
