Change this:

Spoiler

PHP Code:

//When speak Warden..
public bool OnClientSpeakingEx(client)
{
    if (warden_iswarden(client))
    {
        for (int i = 1; i <= MaxClients; i++)
        {
            if(IsClientInGame(i))
            {
                if (GetClientTeam(i) == CS_TEAM_T)
                {
                    SetClientListeningFlags(i, VOICE_MUTED);
                    if(GetUserAdmin(i) != INVALID_ADMIN_ID)
                    {
                        SetClientListeningFlags(i, VOICE_NORMAL);
                    }
                }
            }
        }
    }

    if (hint && GetClientListeningFlags(client) == VOICE_MUTED)
    {
        PrintCenterText(client, "Warden speaks, you have been muted.");
        hint = false;
    } 
}

And will work well. Anyway you can put it the plugin to Github like I have done and I can help you with pull request (or each other)
