Dual-Sound Card instance in Ubuntu

I am a "Voice" enthusiast. I am engaged in education and have a part-time job in the media industry. I also like to make some sound works by myself. Yesterday, I was very excited because my innovative sound card and my dear microphone were finally sent from afar. You can't wait to plug in the sound card and download the driver on WINDOWS. The recording is really great. So I thought about what Ubuntu would look like. Switch to Ubuntu, and the dual sound card is identified. But one problem came to the fore: an innovative sound card could not sound, and I went online to find it,

Yesterday, I was very excited because my innovative sound card and my dear microphone were finally sent from afar. You can't wait to plug in the sound card and download the driver on WINDOWS. The recording is really great. So I thought about what Ubuntu would look like. Switch to Ubuntu, and the dual sound card is identified. But one question came to the fore, that is, the innovative sound card could not sound, and I went online to find a channel with no answer. I asked experts in the group. There was only one answer, and I disabled one in the BIOS, this is obviously not the ideal answer. Do it yourself. The result is as follows.

First, use ls/dev/dsp * to view the sound card and decide the sound card you will use. The result may be as follows:

/Dev/dsp0/dev/dsp1

Next is the operation part.

If it is a command line, you only need to add a/dev/dsp * after-ao.

Example: mplayer-vo xv-ao oss:/dev/dsp xxxx. avi

If the graphic interface is used, it is simpler. In Preferences, go to the Audio page, select oss in Available drivers, and then click

Configure driver: In device, select the sound card you want to use and restart mplayer.

Smplayer makes it easier to switch the sound card. You only need to use-ao oss:/dev/dsp * in "advanced"/"mplayer additional options"/"option" in your preferences, in addition, you can directly switch the sound card without restarting the player.
