alsa-project/alsa-utils issue #126 was opened from marc-hb: >From https://github.com/alsa-project/alsa-utils/blob/c8c348e28a258f17e3/topology/topology.c#L172 ```C static int save(const char *output_file, void *buf, size_t size) { fd = open(fname, O_RDWR | O_CREAT | O_TRUNC, S_IRUSR | S_IWUSR); ``` When using alsatplg in a build system (e.g.: https://github.com/thesofproject/sof/blob/3e1c160e5053eae/tools/topology/topology1/CMakeLists.txt#L243), all other artefacts follow the process's umask **except** alsatplg output. This causes subtle and time-consuming errors when trying to share artefacts across different processes. git blame finds: commit cbabe7a3f0cc84ecd352d4cbf85148946fa6c0d5 Author: Jaroslav Kysela <perex@xxxxxxxx> Date: Thu Dec 19 15:36:05 2019 +0100 alsatplg: rewrite to use the new libatopology functions Before cbabe7a3f0, opening the output file was delegated to library function `snd_tplg_build_file()`. Not sure what permissions were used then. Workaround: ```shell alsatplg -c intput.conf -o - > output.tplg ``` Issue URL : https://github.com/alsa-project/alsa-utils/issues/126 Repository URL: https://github.com/alsa-project/alsa-utils
