since a couple of weeks im using RuneAudio (0.3-beta) on my Cubietruck, to listen to music. Its connected via S/PDIF toslink to a Schiit Modi Uber > Schiit Vali 2 > headphone. My music library is on a NAS with an NFS share via LAN.
In an attempt to reduce the noise from the powersource (5V switching ac/dc powersupply) i started using a lithium polymer battery (from Olimex https://www.olimex.com/Products/Power/BATTERY-LIPO6600mAh/) to power the cubietruck. This works quite well, after modifying the fex file to the 6600mAh of the battery.
What im wondering is, which modules in the fex file are safe to disable to not affect audio playback (via s/pdif)?
My goal is to disable as many unused functions to save battery time and maybe reduce noise added to the audio signal by these unused chips. Rune keeps functioning if i disable [wifi_para], [bt_para], [ir_para], [sata_para], [hdmi_para], [tvout_para] and [mali_para]. I'm not an advanced (Arch)Linux user, so i dont know what the effects are on the OS. I noticed a little longer boot time when i disabled [hdmi_para], [tvout_para] and [mali_para].
Thanks in advance, any tips / knowledge is welcome.
