No sound at either end

Hi, I've set up the session with my bass player and JamLink mixer shows that we are jamming, but there seems to be no sound at either end. Both of us can hear ourselves in headphones, but not each other. Is there anything I am doing wrong? I also tried to downgrade the firmware to 0.7 - did not help. Help anyone?

we switched to UDP instead of "both" protocols. It worked when we made the switch.


When jamLink users connect but can not hear the remote player(s) in their headphones, they often have a port mapping issue in their home router.

Configuring port mapping varies from router to router, but is relatively easy to do.

1. determine the IP address of your jamLink by looking at your router's dhcp table and matching the jamLink MAC address with the corresponding IP address entry in the dhcp table.

2. set an IP address reservation in your router's dhcp table for the IP address of the jamLink which you just discovered.

3. map UDP/TCP port 4464 internal and external to the IP of the jamLink which you just found in your dhcp table and reserved for the jamLink in your dhcp reservations list.

These are just the very basic steps you need to take to create the port mapping to your jamLink in your router. If you have trouble doing this, please give us a call or send us an email requesting a time to have one of us walk you through the setup.


After configuring our routers on both ends as described above, we still have no sound at either end. Something is still strange though. I will show up in the mixer panel on the other end but they are not showing up in mine. when I click on their user name to request a jam session, either nothing happens or I get a message that they are already jamming, but they still don't show up in my mixer panel.. any suggestions?

...and I'm blaming my router. I have a Linksys WRT54GS with the Gargoyle operating system on it. It's a really cool way to bring this older router back to being useful, but I am betting the firewall function of it is breaking the JamLink's functionality.

It just so happens I have a new Linksys E2000 that I am going to try next. I'll post back here if I get it working.

"To be honest with you, my grandfather stolen out of the share he did not have time to glance lie was that the Yankees have passed, you this question I really can not answer you." I thought to myself, you do not easily fooled, Wink also put on special sincere way. The old man really believed that gold teeth, sighed: "It was not coincidence, that seems not to find that Americans probably really did not expect it." "How, how do you so concerned about this volume?" I asked, this is too strange, this collection of ancient books to see the fate of all, want the Warring States period of ancient set of 20 volumes are found, it is also a bit too greedy a. "Little Brother, tell you the truth, I really was not fighting back, you see my body bone, which toss enough ah, but my friend is really expert, I do not know what he was selling off the child, in short, , people have the people the truth. "He chuckled and shook his head," we are not a lot to ask, right, take one step ahead. "Having left without looking back. I looked down, he goes on copy paper in my hand, and suddenly, I found a pattern in that paper, it was a fox like face, two eyes, no pupil is very three-dimensional, as if from that Like the paper out of the recess, I see a breath, which I've never seen a silk book, it should be a treasure. I reflected on the old itch out, we use this to do a few copies of fake enough rubbing my music. Zhang went to the door hastily busy one, look at old man was back in time to that gold teeth. I thought he must have come back to take this stuff, busy ran back, picked up a digital camera to shoot it down, and then head out the door to pick up the paper. The face of the old man's nose hit the big gold teeth: "You forgot something." I said. My grandfather Changsha earth Master, which is the general said, "grave robbers." My grandfather into this line of reason is not surprising, with the words now that the hereditary line of business.

With this was issued, by way of supplement, an address from Ginckle himself; more brief and more pertinent, offering rewards to deserters from the royal army, who would renounce their allegiance, and take service under his standard. To soldiers serving without pay, as those of the Irish army had been for several months, this twofold inducement of amnesty and reward was a terrible temptation; but it had little or no effect. The defection caused by St. Ruth's misconduct before Athlone had already done its worst, and the desertion rather tended to O'Donnell behind them, than to Ginckle in their front. Others, preferring a middle course, had joined the Rapparees, and the rest, true to their antecedents, resolved to retrieve their cause in the field, or depart the country forever. Of the manifesto of the Lords-Justices, it may be finally said, that had it been meant in good faith, it would have won for them a very fair claim to justice and humanity. But when it is known that all their proffers were illusory, and that their subsequent conduct was cruel beyond description; that the lands to which they had promised reinstatement had already been sequestrated beyond redemption; that the plighted faith of themselves, the general, and their sacred Majesties were wantonly violated; and that a hundred years of more than barbaric cruelty elapsed after their "Majesties had found it convenient to convene a Parliament;"—the character of all—Lords-Justices, general, and "Sacred Majesties"—is too infamous for a single epithet. On the same day that those proclamations were issued, Captain Villers returned from a reconnoissance, and reported St. Ruth as still holding the passes of the river Suck, and apparently determined to dispute them. But it being deemed advisable to give these missives time for the desired effect, a further postponement of action was the consequence, and the interval was spent in endeavoring to repress the excesses of the army. All religious exhortations having failed, a stringent military code was adopted. This held forth at once the severest punishment for crime, and the most liberal promises of booty and reward to the men, and of "lands and livings" to the officers. This comported so strangely with the "amnesty," etc., of the Lords-Justices, as to render it entirely nugatory, by exposing their covert hypocrisy in the same breath in which their manifesto was announced.
