Any ideas on how to get 384 kHz/32bit working with Max2Play?
When I use alsacap I can see …
`[email protected]:~# alsacap -c 1
*** Scanning for playback devices ***
Card 0, ID
Device 0, ID
PianoDACPlus multicodec-0', name‚, 1 subdevices (1 available)
2 channels, sampling rate 8000..192000 Hz
Sample formats: S16_LE, S24_LE, S32_LE
Subdevice 0, name
And if I look into allo.tar I can see that the firmware only goes up to 192000.
And if I look at https://github.com/raspberrypi/linux/pull/1460 (Enable 352k8 and 384k sample rates for I2S connected boards/HATs that support those rates) it seems that others are also trying…. I also saw notes about Rune and Moode v3.0 supporting these rates from http://dietpi.com/phpbb/viewtopic.php?f=9&t=900&p=4073
I have installed m2p_rpi3_allo_238_wps.img and are now running version Beta-170103 on a Raspberry PI 3.16. Januar 2017 at 17:28 #25974
So sorry about the late response. Unfortunately, we do not currently have a fix to support these extremely high sample rates. However, if you find a fix that could be implemented, let us know and we will look into it.16. Januar 2017 at 21:43 #25990
Looks like Clive has already done a patch for this too, https://patchwork.kernel.org/patch/9186213/
Do you see any issues if I compile this up and give it a go?20. Februar 2017 at 15:09 #27046
Sorry about the late response. Have you tried it, yet? As mentioned, we have not had any experience with these high sample rates. Feedback would be appreciated.
