[alsa-devel] Intel ICH7/Realtek ALC262 on MSI MS-7290 (Crystal 945)

[Matthew Hurne]

The company I work for has informed me that they will gladly provide funding to someone who will tackle this issue and get ALSA working properly on this unit. We have no interest in owning any code; we just need to get audio working on the unit - so you would be paid for your time, not your code - that would, of course, belong to the ALSA community.
