close() closes the file descriptor hence your EBADF for the following read.

As a suggestion, once you use close, actually or mentally put -1 into the file descriptor variable. This also acts as a massive hint that the file descriptor is no longer valid.

Did you really mean "shutdown()" ?

NAME
aseqnet - ALSA sequencer connectors over network SYNOPSIS
aseqnet [remotehost] DESCRIPTION
aseqnet is an ALSA sequencer client which sends and receives event packets over network. Suppose two hosts connected by network, hostA as a server and hostB as a client. The ALSA sequencer system must be running on both hosts. For creating the server port, run the following on hostA: hostA% aseqnet sequencer opened: 128:0 Then a user client 128 with port 0 was opened on hostA. (The client number may vary.) For creating the (network-)client port, run aseqnet with the hostname of the server: hostB% aseqnet hostA sequencer opened: 132:0 Now all events sent to hostA:128:0 are transferred to hostB:132:0, and vice versa. The ports created by aseqnet can be connected arbitrary to other sequencer ports via aconnect(1). For example, to connect hostB:132:0 to a MIDI output device 65:0: hostB% aconnect 132:0 65:0 Then events to hostA:128:0 will be delivered to hostB:65:0. The following command plays MIDI on hostB. hostA% pmidi -p 128:0 foo.mid The multiple clients may exist simultaneously. If hostC is connected as a client to hostA, events from from hostA are sent to all con- nected network clients, i.e. hostB and hostC. However, only one connection is allowed from a client to a server. To disconnect network, stop all clients before server by ctrl-C or sending signal to them. The server will automatically quit. OPTIONS
-p port Specify the TCP port number or TCP service name. -s addr Subscribe to the given address for read automatically. -d addr Subscribe to the given address for write automatically. -v Verbose mode. SEE ALSO
