Re: [Alsa-user] Sound Blaster Audigy Series only working in 50% of the boots

[Patrick M. <dus...@gm...>]

Hello,

I don't think this is likely to help your issue, but if you haven't 
already, you should try booting linux with the option iommu=soft

That was necessary for an issue I had with another card that uses the 
snd-emu10k1 driver.

Sorry if it doesn't help.
