def print_client(client)
  tags = {
    type: client.type,
    card: client.card,
    pid: client.pid
  }.compact.map { |k, v| "#{k}=#{v}" }.join(',')
  lines = ["#{client.id} => #{client.name} [#{tags}]"]
  client.ports.each do |port|
    if port.connected_to_type
      connected = "connected to #{port.connected_to_type} #{port.connected_to_client_id}:#{port.connected_to_port_id}"
    else
      connected = 'not connected'
    end
    lines.push "  #{port.id} => #{port.name} (#{connected})"
  end
  puts(*lines, '')
end

input_clients = ALSA::Aconnect.input_clients
puts "Inputs:"
input_clients.map { |client| print_client(client) }

output_clients = ALSA::Aconnect.output_clients
puts "Outputs:"
output_clients.map { |client| print_client(client) }

input = input_clients.detect { |c| c.name = 'My Input' }.ports.detect { port.name == 'My Input Port' }
output = input_clients.detect { |c| c.name = 'My Output' }.ports.detect { port.name == 'My Output Port' }
ALSA::Aconnect.connect(input, output)

ALSA::Aconnect.disconnect(input, output)

ALSA::Aconnect.connect("#{input.client.id}:#{input.id}", "#{output.client.id}:#{output.id}")
ALSA::Aconnect.disconnect("#{input.client.id}:#{input.id}", "#{output.client.id}:#{output.id}")
```
