[help wanted] USB sound card rate problem

[eerozeteen]

Hi, Im trying to make librespot to work with my raspberry pi media center. Im using 2 sound cards in my RPi - first is digi+ for kodi output, and second is cheap usb audio for playing music. Unfortunately my usb card can ony use 48kHz audio:

osmc@osmc:~$ cat /proc/asound/card1/stream0 Elan USB Audio at usb-3f980000.usb-1.4, full speed : >USB Audio

Playback: Status: Stop Interface 1 Altset 1 Format: S16_LE Channels: 2 Endpoint: 1 OUT (ADAPTIVE) Rates: 48000

Capture: Status: Stop Interface 2 Altset 1 Format: S16_LE Channels: 2 Endpoint: 2 IN (SYNC) Rates: 48000`

And when i try to play music from spotify, i get:

[...]

DEBUG:librespot::player: command=Play ALSA lib pcm.c:7935:(snd_pcm_set_params) Rate doesn't match (requested 44100Hz, get 48000Hz) thread '' panicked at 'called Option::unwrap() on a None value', /checkout/src/libcore/option.rs:323 note: Run with RUST_BACKTRACE=1 for a backtrace. DEBUG:librespot::player: drop Player[1] [...]

Is it possible to make spotify/librespot to use 48kHz? Or make some magic to get 44,1kHz on my USB card? When i use my digi+ card as output, everything works. My basic asound.conf is:

pcm.!default { type hw card 1 }

ctl.!default { type hw
card 1 }

I was try to use somthing like that in asound.conf, but probably i cant understand how alsa work and how to configure it correct.

pcm.!default { type hw card 1 type rate slave { pcm "plughw:1,0" rate 44100 } }

ctl.!default { type hw
card 1 type rate slave { pcm "plughw:1,0" rate 44100 }

I know that it isnt librespot problem, but maybe someone have same problem and resolve it.
