Problems with soundblaster16

486 DX4/100 running linux-1.3.35 with the following :

SMC ethernet card (IRQ 10)
Orchid Kelvin 64 Graphics card
UltraStor 34F scsi card (IRQ 11)

problem is with the soundblaster card:
IRQ7, DMA1 & 6, addresses 0x220 and 0x330...

insmod sound seems to work fine. From dmesg:

Sound initialization started
snd2 <SoundBlaster 16 4.13> at 0x220 irq 7 drq 1
snd6 <SoundBlaster 16 4.13> at 0x220 irq 7 drq 6
snd7 <SoundBlaster MPU-401> at 0x330 irq 7 drq 0
Sound initialization complete

However, playing sounds (cat .au > /dev/audio) gives error messages (I/O
error) and sometimes loops back sound from previous attempts at playing
sounds.

Removing the sound module (rmmod sound) gives the following result in
dmesg:

Sound unload started
sound_free_dma: Bad access to DMA channel 1
Sound unload complete

Can anyone suggest anything that I may be doing wrong here? Thanks.
