I've had no problems with my SB16 up to 2.1.86... but on 2.1.88 the
sound comes in packets... like

normal-audio... delay.... normal-audio... delay.... (repeat)

My bootup messages says:

kernel: sb: Interrupt test on IRQ7 failed - Probable IRQ conflict
kernel: <Sound Blaster 16 (4.13)> at 0x220 irq 7 dma 1,5
kernel: <Sound Blaster 16> at 0x330 irq 7 dma 0
kernel: <Yamaha OPL3 FM> at 0x388

...but it's always worked on IRQ 7 before... ...and I don't have
printer supported enabled to IRQ 7 shouldn't be grabbed by the printer

Here's my /dev/sndstat:
