Hi all,

While reading alsa-lib sources I've spotted some strange code in src/pcm/pcm_route.c: /* 3 bytes formats? */ route->params.use_getput = (snd_pcm_format_physical_width(src_format) + 7) / 3 == 3 || (snd_pcm_format_physical_width(dst_format) + 7) / 3 == 3;

Since snd_pcm_format_physical_width() returns a width in bits it seems to me that this would mean formats that are between 2 and 4 bits (inclusive) wide.

Before commit de63b942acf520 ("pcm: route: Use get/put labels for all 3 byte formats") this read as: route->params.use_getput = snd_pcm_format_physical_width(src_format) == 24 || snd_pcm_format_physical_width(dst_format) == 24;

The commit message of that commit says that this change was supposed to set this flag also for 18 and 20-bit physical width formats.

Is there a mistake in this code or am I wrong somewhere in my thinking?

Best regards, Maciej
