Dear all, Using a TerraTec EWS88MT (ice1712), I want to record simultaneously from four different stereo sources. Although the break-out box is equipped with 8 analogue inputs, I do not know which devices correspond to the inputs. Apparently, there are only two capture devices, and it seems to be impossible to create additional capture devices because /dev/snd is a symbolic link to /proc/asound.
# ls -l /dev/snd/ total 0 crw-rw-rw- 1 root root 116, 0 Dec 4 15:16 controlC0 crw-rw-rw- 1 root root 116, 8 Dec 4 15:16 midiC0D0 crw-rw-rw- 1 root root 116, 24 Dec 4 15:16 pcmC0D0c crw-rw-rw- 1 root root 116, 16 Dec 4 15:16 pcmC0D0p crw-rw-rw- 1 root root 116, 25 Dec 4 15:16 pcmC0D1c crw-rw-rw- 1 root root 116, 17 Dec 4 15:16 pcmC0D1p crw-rw-rw- 1 root root 116, 18 Dec 4 15:16 pcmC0D2p crw-rw-rw- 1 root root 116, 1 Dec 4 15:16 seq crw-rw-rw- 1 root root 116, 33 Dec 4 15:16 timer # arecord -l card 0: 88MT [TerraTec EWS 88MT], device 0: ICE1712 multi [ICE1712 multi] Subdevices: 1/1 Subdevice #0: subdevice #0 card 0: 88MT [TerraTec EWS 88MT], device 1: ICE1712 consumer [ICE1712 consumer] Subdevices: 1/1 Subdevice #0: subdevice #0 So far, I tried to define four PCM devices stereo0, stereo1, stereo2, stereo3 in /etc/asound.conf (see below), and used commands like arecord --device="stereo0" -t wav -c 2 -f cd -d 20 test0.wav & arecord --device="stereo1" -t wav -c 2 -f cd -d 20 test1.wav & arecord --device="stereo2" -t wav -c 2 -f cd -d 20 test2.wav & arecord --device="stereo3" -t wav -c 2 -f cd -d 20 test3.wav & However, the files were not recorded simultaneously but sequentially and did not contain any audible content. I would be glad about any hints what I did wrong. Kind regards, Ulrich Latzenhofer ----- This is my /etc/asound.conf: pcm.ice1712 { type hw card 0 } ctl.ice1712 { type hw card 0 } pcm_slave.stereo { pcm ice1712 } pcm.stereo0 { type plug slave stereo route_policy default ttable.0.0 1 ttable.1.1 1 } ctl.stereo0 { type hw card 0 } pcm.stereo1 { type plug slave stereo route_policy default ttable.2.0 1 ttable.3.1 1 } ctl.stereo1 { type hw card 0 } pcm.stereo2 { type plug slave stereo route_policy default ttable.4.0 1 ttable.5.1 1 } ctl.stereo2 { type hw card 0 } pcm.stereo3 { type plug slave stereo route_policy default ttable.6.0 1 ttable.7.1 1 } ctl.stereo3 { type hw card 0 } ------------------------------------------------------- This sf.net email is sponsored by:ThinkGeek Welcome to geek heaven. http://thinkgeek.com/sf _______________________________________________ Alsa-user mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/alsa-user
