Error: Block subscription failed

Caused by:
    Got error from JSON-RPC: JsonError { jsonrpc: String("2.0"), id: Number(1258843258798613412), error: JsonErrorVal { code: Number(-32603), message: String("Internal error") } }

I have tried the commands from https://darkrenaissance.github.io/darkfi/testnet/payment.html. I don't know exactly what happened, all of a sudden the message JSON-RPC error: "Blockchain is not synced" appeared and then I saw that the other process crashed.

[aggstam]

Are you on master or tag 0.4.0?
The JSON-RPC error: "Blockchain is not synced" is because wallet needs to be synced with current blockchain state, via subscribe or ./drk scan.

[marek22k]

I use the 0.4.0 tag as in the instructions. I think the blockchain is not synced is caused by the crash of subscribe.

[aggstam]

Use the master tag, we are fixing findings and will tag a new version once everything is stable.
Let us know if issues persist.

[a-moreira]

in v4.0.1 I can still see these errors, although it hasn't crashed (yet)

@a-moreira:
Do you have libmpg123-dev installed?
These errors do not affect rest functionality.

[a-moreira]

@aggstam I do have it installed.

$ apt install libmpg123-dev
Reading package lists... Done
Building dependency tree
Reading state information... Done
libmpg123-dev is already the newest version (1.25.13-1).

I also have libout123 installed (found a reference to this lib while searching for the error).

You are right that it doesn't seem to impair functionality. Also the error seems to appear randomly.

[aggstam]

@a-moreira Its not as random as you might think :)
TLDR: terminal is not able to get sound driver lock to play a sound, as its locked by some other app.
