Fix HDMI audio lag on Retina MacBookPro 2013 (macbook11,1) in Linux

The problem

The HDMI out works just fine out of the box, except that you’ll notice that unless you boot with the HDMI cable connected, you’ll experience some weird audio lag through HDMI. Even worse, after a few seconds, HDMI audio will simply stop working.

Audio drift, lag, and eventually no audio. To rub some salt into the wound, this does not happen under macOS. Classic.

The solution

Well, the good news is that you can get this fixed. Turns out this is because of Linux kernel bug #60769. I can’t comment on the details of how and why the IOMMU feature breaks this particular combination of videocard/HDMI/audio, but I can tell you how to work-around this.

To fix, or at least work-around this, you have to edit your /etc/default/grub and add intel_iommu=on,igfx_off to your kernel boot options:

GRUB_CMDLINE_LINUX_DEFAULT="(...) intel_iommu=on,igfx_off"

Please let me know in the comments, or @diegoe on Twitter, if this helped you, or if you have any insight on why this happens, I’m curious.

Some months with the Fujifilm XF35mm F1.4

A few months ago, Fujifilm had a big sale of lenses and gear, with some drastic discounts like the famous XF35mm F1.4 lens.

Although I couldn’t take advantage of the discounts in the US, I was able to get this lens for a similar price in the local Fujifilm distributor (which I had no clue existed).

Six months later, here are my thoughts on this lens.

Carteles de la marcha: #KeikoNoVa, vol. 3

El domingo en Perú se escoge entre continuar con la democracia que tantas cosas buenas nos ha traído, o retroceder hacia la dictadura y la corrupción.

Cuando haya viajeros del tiempo turistas, los peruanos del futuro vendrán a esta semana a entender cómo se salvó, o se acabó de joder, el Perú.

Pero hasta que eso suceda, vota por PPK. La moral personal no se puede poner como excusa para mirar hacia otro lado, lavarse las manos, y dejar que secuestren al Perú aquellos que lo destruyeron en los años noventa.

Fujimori nunca más, vol. 2: #KeikoNoVa

La segunda marcha contra Fujimori, y todo lo que representan. Lo especial de esta edición es que se programó en el aniversario 24 del autogolpe de Fujimori que inició su dictadura.

El número de asistentes se dice entre 50 y 60 mil personas. Fueron unas 5 a 10 cuadras de gente marchando por todo el centro de Lima.

Aquí un recuento de los carteles curiosos.

Fujimori nunca más: #KeikoNoVa

El viernes 11 de marzo estuve en la marcha contra la candidatura de Keiko Fujimori, hija del exdictador Alberto Fujimori.

Pensaba explicar en un párrafo por qué la gente no quiere que Keiko ni siquiera postule pero creo que las fotos lo explican.

Fujimori es una de las peores cosas que le pasó a Perú, y Keiko no es más que la versión actualizada con USB3.0.

Domke F-5XB: A minimalist shooting bag. One year review

The Domke F-5XB (700-52A) is a very popular bag with photographers and it’s a perfect fit for shooting with a minimalistic setup. It’s very well built and has a “no bullshit” philosophy that’s perfect for grab and go shooting.

I have used this bag for a year now, and it’s the perfect time to share my thoughts on this nice piece of gear.

Think Tank Photo Mirrorless Mover 30i: A two year review

The Mirrorless Mover 30i is Think Tank Photo’s roomiest bag in the Mirrorless Mover line. It’s also my first ever Think Tank Photo bag. Two years after I first got it, I finally managed to sit down and write a review of it for my use case of photo and video work.

El sábado estuve en la marcha en favor de la aprobación de la #UniónCivil.

La UniónCivil es un proyecto de ley que permitiría a personas del mismo sexo recibir y ejercer (casi) los mismos derechos que una pareja heterosexual tiene.

Esos derechos son cosas que suenan tan obvias como: herencias, decisiones médicas, financieras. Es el primer paso a una total igualdad ante la ley y el estado.

Como siempre, hay un grupo de personas en el lado incorrecto de la historia. Por ignorancia, o hasta malicia, le cuesta a muchos entender por qué esto es importante.

Pasó con la abolición de la esclavitud, con el voto para las mujeres, con el divorcio.

La historia le va a dar la razón a aquellos que hoy votan y apoyan la igualdad de derechos para todos.

Did Bukowski really said “Find what you love and let it kill you”?

While chatting about life and meaning with my still blog-less friend Pedro, I recalled the “famous” quote which according to most of the internet was written by Bukowksi in a letter:

My dear,

Find what you love and let it kill you. Let it drain from you your all. Let it cling onto your back and weigh you down into eventual nothingness. Let it kill you, and let it devour your remains.

For all things will kill you, both slowly and fastly, but it’s much better to be killed by a lover.

Falsely yours,
Henry Charles Bukowski”

I wasn’t able to find out if the quote was really from the poet himself, or just a typical invention of the internet.

In doubt, I simply labeled the letter to be misattributed since I had no further evidence to support its authenticity.

Turns out I wasn’t the only one to ask myself this question, but “Jef with one F” from HoustonPress actually got to the bottom of the matter:

The earliest source we could find for the phrase came from the April 1998 issue of CMJ New Music Monthly. In it David Grubbs interviewed Van Dyke Parks. Parks was asked about how he went about crafting a song, and he went on a roundabout answer involving trial and error and a fear that something wouldn’t work.

“It’s like my friend Kinky Friedman said,” mused Parks. “You’ve got to find what you love and let it kill you. I don’t think any of us should ever forget that.”

When contacted about Friedman being the original source, Friedman’s publicist Cleve Hattersley responded, “Kinky has assured me it is a pure Kinky-ism.”

I guess it’s myth busted… Up until the attribution to Bukowski. For all we know, Mr. Friedman could be pulling our leg :).
