So, because of some hardware issues I'm having, I need to disable Android's HDMI Digital Audio Output and let only the analog sound card of my A10 chipset work. Just for info - the issue is that there's no cable plugged into the HDMI output of my tablet, but the Android is recognising that there's something plugged into the port and as soon as I wake up the tablet, it redirects the audio output through HDMI Digital Audio out.
Now for my actual problem.. I'm trying to change /proc/asound/cards or /proc/asound/pcm The filesystem (/system) is mounted as rw, I do have root access, ES File Explorer is with "Root Explorer" turned on and as soon as I click Save, it backs up the old contents of the file. Also, the folders and the files that I'm trying to modify are with 777 permissions and owned by root.
Of course, I tried through ADB push and the same shi* happens. What it can be?
