The Alsa documentation is confusing me massively. I have no problems getting a basic setup sorted but I'm having trouble when trying to do more than one thing at a time. I have 2 soundcards: - via686 onboard (half-duplex hardware. Can only record OR playback, can only playback one thing at a time atm) - ymfpci (should be full-duplex. Can play back more than one thing at a time. Should be able to record whilst playing back) One way or another I need to record whilst playing back and be able to playback from >1 source (i.e. play 2 mp3 files at once). To do this: - How do I go about setting up /dev/dsp1 as well as /dev/dsp? (I have edited /etc/modules.d/alsa and update-modules to no avail. Can I do this with seporate soundcards or just one? (the ymfpci has 2 channels) - How do I get my yamaha to record whilst playing back (full-duplex)? I have followed install instructions and I think it should work Any links or suggestions would be great. I'm finding Alsa incredibly compilcated for me. Perhaps (as the most simple answer) I could have the via686 using standard OSS and the ymfpci using Alsa? ------------------- details to follow:- ------------------- #lsmod snd-pcm-oss 36804 1 snd-mixer-oss 9184 0 [snd-pcm-oss] joydev 6816 0 (unused) input 3424 0 [joydev] snd-opl3-synth 8604 0 (unused) snd-seq-instr 4432 0 [snd-opl3-synth] snd-seq-midi-emul 4560 0 [snd-opl3-synth] snd-seq 37868 0 [snd-opl3-synth snd-seq-instr snd-seq-midi-emul] snd-ainstr-fm 1540 0 [snd-opl3-synth] ppdev 8292 0 (unused) lp 6176 0 (unused) hid 15072 0 (unused) sr_mod 11864 0 (unused) apm 9608 1 uhci 24296 0 (unused) vfat 10780 0 (unused) fat 32056 0 [vfat] parport_pc 13252 1 parport 14208 1 [ppdev lp parport_pc] printer 7488 0 (unused) scanner 8512 0 (unused) NVdriver 1065920 10 ide-scsi 7680 0 eepro100 17456 1 snd-via686 7076 0 snd-ymfpci 41664 1 snd-pcm 56256 0 [snd-pcm-oss snd-via686 snd-ymfpci] snd-ac97-codec 24432 0 [snd-via686 snd-ymfpci] snd-mpu401-uart 2736 0 [snd-via686 snd-ymfpci] snd-rawmidi 12896 0 [snd-mpu401-uart] snd-opl3-lib 5408 0 [snd-opl3-synth snd-ymfpci] snd-timer 10688 0 [snd-seq snd-pcm snd-opl3-lib] snd-hwdep 3712 0 [snd-opl3-lib] snd-seq-device 3936 0 [snd-opl3-synth snd-seq snd-rawmidi snd-opl3-lib] snd 25928 0 [snd-pcm-oss snd-mixer-oss snd-opl3-synth snd-seq-instr snd-seq snd-via686 snd-ymfpci snd-pcm snd-ac97-codec snd-mpu401-uart snd-rawmidi snd-opl3-lib snd-timer snd-hwdep snd-seq-device] # cat /etc/modules.d/alsa # Alsa 0.9.X kernel modules' configuration file. # $Header: /home/cvsroot/gentoo-x86/media-sound/alsa-driver/files/alsa-modules.conf,v 1.3 2002/06/24 18:05:58 agenkin Exp $ # ALSA portion alias char-major-116 snd # OSS/Free portion alias char-major-14 soundcore ## ## IMPORTANT: ## You need to customise this section for your specific sound card(s) ## and then run `update-modules' command. ## Read alsa-driver's INSTALL file in /usr/share/doc for more info. ## ## ALSA portion alias snd-card-0 snd-ymfpci alias snd-card-1 snd-via686 #alias snd-card-2 snd-ymfpci #alias snd-card-3 snd-via686 #alias snd-card-4 snd-ymfpci #alias snd-card-5 snd-via686 #alias snd-card-6 snd-ymfpci #alias snd-card-7 snd-via686 ## OSS/Free portion ## alias sound-slot-0 snd-card-0 ## alias sound-slot-1 snd-card-1 ## # OSS/Free portion - card #1 alias sound-service-0-0 snd-mixer-oss alias sound-service-0-1 snd-seq-oss alias sound-service-0-3 snd-pcm-oss alias sound-service-0-8 snd-seq-oss alias sound-service-0-12 snd-pcm-oss ## OSS/Free portion - card #2 alias sound-service-1-0 snd-mixer-oss alias sound-service-1-8 snd-seq-oss alias sound-service-1-12 snd-pcm-oss #alias /dev/dsp1 snd-pcm-oss? or something? ...? ----- Thank you for your time.
