X-BeenThere: freebsd-multimedia@freebsd.org X-Mailman-Version: 2.1.5 Precedence: list List-Id: Multimedia discussions List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Mon, 29 Oct 2007 18:16:49 -0000 Hi all, I've recently updated my somewhat aged 6.2-STABLE (from March 2007) on my HP nx9005 laptop to a recent -STABLE, which somehow broke sound support. Before, I never had any trouble with sound since 5.2-RELEASE. Went straight on to 7-CURRENT (just a few days before the BETA branch), but the problem persists. It's an Acer Labs M5451 card (snd_t4dwave driver). Problem: playback stops after a few seconds with pcm0:play:dsp0.p1: play interrupt timeout, channel dead Verbose dmesg available here: http://demira.shopkeeper.de/~sascha/nx9005/misc/dmesg-7-verbose My CVS-fu isn't that good yet to track down all the files associated with each sound code change that I'd need to check out to single out a specific commit, so where would be a good start? Cheers, -sascha
