Is IRQ conflicts always evident?

After installing a NIC, my SB AWE 64 doesn’t deliver .wav nor .mp3 anymore.

After fidling with DMA settings I regained the .mdi

The sounds will play for ? or ? a sec. then hang.

Device manager doesn’t report any conflicts or hardware problems.

All my IRQ’s are accounted for, the SB has #9.

System is PII 400 160 Megs and OS is W98SE
