Forgive the ignorance but what sort of string does aplay's "-d" option need? I tried the device names that qjackctl shows me (namely default, hw:0, hw:1,0, hw:1) and only "default" worked (I expected hw:0 also to work since that's the same as default, i.e. the internal card). All other options return immediately with error and don't play. Here's what aplay -l gives: **** List of PLAYBACK Hardware Devices **** card 0: Intel [HDA Intel], device 0: ALC861VD Analog [ALC861VD Analog] Subdevices: 1/1 Subdevice #0: subdevice #0 card 1: Pro [FastTrack Pro], device 0: USB Audio [USB Audio] Subdevices: 1/1 Subdevice #0: subdevice #0 card 1: Pro [FastTrack Pro], device 1: USB Audio [USB Audio #1] Subdevices: 1/1 Subdevice #0: subdevice #0 I tried various device names like "Intel", "HDA Intel", "Pro", "FastTrack Pro", "USB Audio" and they all give the answer "unknown PCM". Device names "hw" "hw:0" "hw:1" "hw:1,0" give this: Playing WAVE 'a11wlk01.wav' : Signed 16 bit Little Endian, Rate 44100 Hz, Mono aplay: set_params:909: Channels count non available If I use the device name "multi" (the name I specified for the virtual device) I get ALSA lib pcm_multi.c:1169:(_snd_pcm_multi_open) Invalid or missing schannel for channel 3 aplay: main:550: audio open error: Invalid argument Grateful for any suggestions - Thanks Dan _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx http://lists.linuxaudio.org/mailman/listinfo/linux-audio-user
