The manpage for modprobe mentions that dashes and underscores are treated interchangeably in module names. The stack trace dumps seem to print module names with underscores. Use bash to replace _ with the pattern [-_] so that file names with dashes or underscores can be found. For example, this line: [ 27.919759] hda_widget_sysfs_init+0x2b8/0x3a5 [snd_hda_core] should find a module named snd-hda-core.ko.
