In this case, it's correct - thanks for the suggestion.
hw results in plughw being used:
Code:
--------------------
squeezelite -s localhost -o "hw:CARD=ES9023" -d all=info -p 40
[16:18:26.905117] alsa_open:389 opened device hw:CARD=ES9023 using format:
S16_LE sample rate: 48000 mmap: 1
[16:18:26.905207] alsa_open:468 buffer: 40 period: 4 -> buffer size: 1920
period size: 480
[16:19:32.588500] alsa_open:338 opening device at: 44100
[16:19:32.589280] alsa_open:368 reopening device hw:CARD=ES9023 in plug mode
as plughw:CARD=ES9023 for resampling
[16:19:32.591067] alsa_open:389 opened device plughw:CARD=ES9023 using
format: S16_LE sample rate: 44100 mmap: 1
--------------------
So I tried:
Code:
--------------------
squeezelite -s localhost -o "plughw:CARD=ES9023" -d all=info -p 40
[16:21:33.497244] output_init_common:411 supported rates: 384000 352800
192000 176400 96000 88200 48000 44100 32000 24000 22500 16000 12000 11025 8000
[16:21:33.578703] alsa_open:389 opened device plughw:CARD=ES9023 using
format: S32_LE sample rate: 44100 mmap: 1
--------------------
Both work fine, with no errors and very low CPU utilization.
However, since the soxr resampling has better quality (see 'here'
(http://src.infinitewave.ca/)), I'll be using this:
Code:
--------------------
squeezelite -s localhost -o "hw:CARD=ES9023" -d all=info -R -u vE -p 40
[16:49:46.185966] output_init_common:411 supported rates: 48000
[16:49:46.315986] resample_init:362 resampling sync recipe: 0x06, flags:
0x00, scale: 0.89, precision: 0.0, passband_end: 0.00000, stopband_begin:
0.00000, phase_response: -1.0
[16:49:46.817425] resample_newstream:189 resampling from 44100 -> 48000
--------------------
CPU load is a bit higher, but still negligible (~8% on a RPi)
