# @NOTimothyLottes — Did manage to get ALSA to function without SNDRV_PCM_IOCTL_HW_REFINE and only wi

Did manage to get ALSA to function without SNDRV_PCM_IOCTL_HW_REFINE and only with SNDRV_PCM_IOCTL_HW_PARAMS. My structures are different but aliased (snd_interval.interger -> .flag=4). Apparently setting the core values is enough for the driver.

Don't actually have to set {.flags,.rmask,.info} on my machine. Absolutely do have to set ".max=~0" for the intervals not being hardcoded. I only do double buffered, 48000Hz stereo, and just vary the frames/period sizing.
