NetWinder has no hardware support for those, and ebsa285 appears to not support them in Linux, as the XBUS is not set up that way and there is no support for a PCI-ISA bridge. CATS on the other hand has four ISA slots connected to a PCI-ISA bridge device. Russell mentioned that it is no longer possible to select the sound drivers for Netwinder after this, as the WaveArtist sound chip is connected to the ISA bus. However, the WaveArtist module was removed years ago in linux-4.15 and did not actually depend on CONFIG_ISA. While the SoundBlaster compatibility mode of the SoundChip might work with the ALSA sb16-isa driver with a little help, there is no mixer support without the waveartist driver, and the default settings for sb16 never probe IRQ 3.
