With the following patch set any sound timer can be used as timer source
for the aloop devices if selected. 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.


Best regards,

Timo
