He earned an Oscar nom for "Flags of Our Fathers" and collaborated with the director on 14 films, including "Jersey Boys" and the upcoming "American Sniper."

Walt Martin, a sound mixer who worked with Clint Eastwood on 14 films and received an Oscar nomination for the director's 2006 war drama Flags of Our Fathers, has died. He was 69.

Martin died July 24 of vasculitis after being hospitalized with chest pains at Providence Saint Joseph Medical Center in Burbank, his wife Elena said.

Martin worked with Eastwood most recently on American Sniper, the military drama starring Bradley Cooper that wrapped filming in June and is due out in 2015, and this summer's Jersey Boys musical.

Their collaboration began on True Crime (1999) and continued through Space Cowboys (2000), Blood Work (2002), Mystic River (2003), best-picture winner Million Dollar Baby (2004), the Flags companion film Letters From Iwo Jima (2006), Changeling (2008), Gran Torino (2008), Invictus (2009), Hereafter (2010) and Trouble With the Curve (2012).

Martin was among the small, tight-knit group of creatives whom the director "took everywhere," Gail Carroll-Coe, a boom operator who did seven Eastwood films with the sound mixer, tells The Hollywood Reporter.

Martin's film résumé also includes Last Resort (1986), director John Huston's final film, The Dead (1987), Tremors (1990), Tombstone (1993), Cold Around the Heart (1997), The Banger Sisters (2002), Charlie's Angels (2000) and Hollywoodland (2006). He recently worked on such TV dramas as The Closer, Mad Men and Sons of Anarchy.

Martin shared his best achievement in sound mixing Oscar nom for Flags of Our Fathers with three other Eastwood regulars: John T. Reitz, David E. Campbell and Gregg Rudloff.

In addition to his wife, survivors include a step-daughter, Claudia. A memorial will take place at 12:30 p.m. on Sept. 6 at Forest Lawn in the Hollywood Hills.
