Hello I miss understanding the current audio situation on GNU/Hurd I read the audio article in the Hurd website¹
and I thought it is stoped because I didnt found a source code for it in Hurd repo so I was planning to write an audio interface for GNU/Hurd 1-(https://hurd.ion.nu/open_issues/audio.html) Best wishes Ahmed On Thu, 13 Aug 2026, 03:13 Samuel Thibault, <[email protected]> wrote: > Hello, > > Thanks for your proposal, but I don't understand what this is. > > What is the purpose?
