Can't open soundcard #8

Open tylor-e opened 3 months ago

tylor-e commented 3 months ago

I use hifiberry_dacplus to play music. I can use "aplay xxx.wav" to hear my sound. But when I use snapclient, I configure "- SNAPCLIENT_OPTS=--host 192.168.100.64 --soundcard 1". It shows errors like follows:

how can I fix this?

tylor-e commented 3 months ago

this fixed after I did nothing but went for business for a few days. Which means I shutdown the docker for 3 days.

however, it still cannot play any music. the log shows like below:

I installed snapclient on both iOS and android phone, and both can get sound. I think my server workds well. but why the snapclient on my raspberry pi 3 cannot. Can anyone help?

I use hifiberry_dacplus to play music. I can use "aplay xxx.wav" to hear my sound. But when I use snapclient, I configure "- SNAPCLIENT_OPTS=--host 192.168.100.64 --soundcard 1". It shows errors like follows:

how can I fix this?

Regarding your first error, either the docker host OS is using the device or you specified the wrong device. Try executing snapclient --list within the container and specify the proper id with --soundcard

Regarding error 2 (this is now wild guessing):

Do you have the same timezone / time on all clients. i interpret the error message as if snapclient drops the packages because they are too old?
