[linux-audio-user] mapping alsa devices to oss devices

In my quest to record from the different channels of the Delta 1010LT have come so far that I can address the different hardware inputs using ALSA device names, while using an appropriate /etc/asound.conf file. e.g. I can arecord -f cd -d 5 -D channel2 test.wav and this would record from hardware input channel #2. I have four stereo input channels, e.g channel1 ... channel4, plus the spdif channel. So far, so good. Now I would need a way to map these channels to OSS /dev/dsp interfaces. something like: /dev/dsp1 -> channel1 /dev/dsp2 -> channel2 /dev/dsp3 -> channel3 /dev/dsp4 -> channel4 I understand that I would need to use the kernel module snd-pcm-oss to achieve this. how can I tell this module to map to the appropriate ALSA devices? BTW, the contents of this asound.conf file is: pcm.ice1712 { type hw card 0 device 0 } # adcdac 1&2 pcm.channel1 { type plug ttable.0.0 1 ttable.1.1 1 slave.pcm ice1712 } # adcdac 3&4 pcm.channel2 { type plug ttable.0.2 1 ttable.1.3 1 slave.pcm ice1712 } #adcdac 5&6 pcm.channel3 { type plug ttable.0.4 1 ttable.1.5 1 slave.pcm ice1712 } # adcdac 7&8 pcm.channel4 { type plug ttable.0.6 1 ttable.1.7 1 slave.pcm ice1712 } #SPDIF channels only pcm.ice1712_spdif { type plug ttable.0.8 1 ttable.1.9 1 slave.pcm ice1712 }
