Its contents 28# may change at any time. 29 30# 31# play-interrupts sets the number of interrupts per second when playing. 32# This affects the resolution of various things, such as sample counts. 33# record-interrupts does the same for record interrupts. 34# 35# These may be tuned to get more accurate information by increasing the 36# count. However, the larger the interrupts per second the larger the 37# load on the system. So use this capability cautiously. The audio810 38# driver enforces a maximum and minimum count. 39# 40# It should also be understood that not all interrupt rates are legal. 41# The hardware is restricted to DMA buffers being allocated on certain 42# boundaries. If those boundaries are violated the driver will not be 43# loaded and an error message is entered into the messages log 44# 45# play-interrupts=120; 46# record-interrupts=120; 47 48# 49# The presence of the ac97-speaker property enables the use of a monoaural 50# output, normally intended for use with a speaker phone.
