It can be select by the additional timer_source kernel module parameter: -2 the jiffies timer will be used as done without this patch (default) -1 the sound timer will be selected depending on the linked sound cards (snd_pcm_link()). The sound timer of the first linked card which is not a aloop device nor a dummy device will be used. 0..N Select the sound timer by the card number. This patch set is required for forwarding audio data between a HW sound card and an aloop device without the usage of an asynchronous sample rate converter.
