The saki sabon sigar aikin Sauti Buɗe Firmware 2.2 (SOF), asalin Intel ne ya ƙirƙira don yin watsi da al'adar samar da rufaffiyar firmware don guntuwar DSP masu alaƙa da sarrafa sauti.
Bayan haka, an canza aikin a ƙarƙashin reshen Linux Foundation kuma yanzu ana haɓaka shi tare da haɗin gwiwar al'umma tare da haɗin gwiwar AMD, Google da NXP.
Aikin yana haɓaka SDK don sauƙaƙe ci gaban firmware, direban sauti don Linux kernel, da firmware na waje da aka saita don kwakwalwan kwamfuta na DSP daban-daban wanda, a tsakanin sauran abubuwa, ana samar da majalissar binary ta hanyar dijital.
Saboda tsarinsa na zamani. Za'a iya tura sautin Buɗe Firmware zuwa gine-ginen DSP daban-daban da dandamalin kayan masarufi. Misali, a cikin dandamali masu goyan baya, tallafi ga nau'ikan Intel (Broadwell, Icelake, Tigerlake, Alderlake, da sauransu), Mediatek (mt8195), NXP (i.MX8*), da AMD (Renoir) kwakwalwan kwamfuta sanye take da Xtensa na tushen DSP.
