This explains how to build from source tarballs. If this command returns that you have this module, then you don't need to recompile your kernel. Most modern distros come with soundcore compiled as a module. Of course it also means you have more control of your system. That way you can load and unload the module manually if you have multiple soundcards/вЂ‹devices or if you intend to debug or use cutting edge software which may cause your drivers to halt sometimes. Look in the sound drivers directory and it should be the first option. You must turn on the sound support soundcore module. Read the Kernel-HOWTO for details of how to compile a kernel. There are two ways of getting Linux drivers to work, you can either compile them into the kernel or build them separately as modules. Pcm_substreams:PCM substreams # (1-8) for loopback driver. (array of charp)Д®nable:Enable this loopback soundcard. Index:Index value for loopback soundcard. The module options for snd-aloop description: Second application (using card 0, device 1, substream 0): Example:ДЇirst application (using card 0, device 0, substream 0):

The consequence of this is, that you have to start the problematic application (for example a MMAP-only game using snd-pcm-oss) first. Therefore no rate, format or channel number conversion is done. The first application opening one device, will force the second application, trying to open the other device, to use its established parameters. Each device can have up to 8 substreams, which means, you can have up to 8 independent loopback connections. This driver provides a pair of cross-connected devices, forming a full-duplex loopback soundcard.
