alsa-project/alsa-lib issue #251 was opened from tramchamploo:
`# # Place your global alsa-lib configuration here... # # pcm.er4s { # Direct hardware access type hw
# Loopback card name # # Has to match "id" in the options of the snd-aloop module card "Loopback"
# Loopback device ID device 0
# Number of audio channels # # Has to match the number of channels in music player app # and in the CamillaDSP input configuration channels 2
# Format of audio stream # # Has to match the format defined in the # of the CamillaDSP input configuration format "FLOAT_LE"
# Sampling-rate of audio stream # # Has to match the sampling-rate defined in the # CamillaDSP configuration rate 48000 }
ctl.er4s { type hw card "Loopback" } ` This is the .asoundrc I'm using, it worked before this update. Now aplay -L doesn't show this device. Using mpd to play to the Loopback gets `snd_pcm_hw_params() failed: Invalid argument`.
Btw, alsa should really have a detailed specification on asoundrc file. The value of the format option I specify is from a dsp project, otherwise I have no idea what to write here. And according to [https://www.alsa-project.org/alsa-doc/alsa-lib/group___p_c_m.html#gaa14b7f26...) it's in a totally different format.
