If there is no soundcards on the target (e.g. qemu), the pkp_postinst function will report an error: alsactl: load_state:1735: No soundcards found... pkg_run_script: package "alsa-state" postinst script returned status 19. opkg_configure: alsa-state.postinst returned 19. Pass '-g' option to alsactl to ignore this error.

QEMU Emulation Targets ====================== To simplify development, the build system supports building images to work with the QEMU emulator in system emulation mode. Several architectures are currently supported in 32 and 64 bit variants: * ARM (qemuarm + qemuarm64) * x86 (qemux86 + qemux86-64) * PowerPC (qemuppc only) * MIPS (qemumips + qemumips64) Use of the QEMU images is covered in the Yocto Project Reference Manual. The appropriate MACHINE variable value corresponding to the target is given in brackets.
