Does ALSA work (without JACK)?

Reviving an old thread -- I just found out about this and it looks quite interesting, esp given my recent positive experience running Fedora RPMFusion and PlanetCCRMA audio apps on Meego ( http://lalists.stanford.edu/lau/2010/09/0502.html ): http://wiki.meego.com/ARM/Meego_on_Beagleboard_from_scratch http://wiki.meego.com/ARM/Meego_on_Beagleboard_from_scratch#Audio ---------- ------------ ------------- ------------ --------- Audio Audio does not yet work on beagleboard XM. Audio works on beagleboard revA, revB and revC out of the box, but is muted by default. It can be enabled using the alsamixer tool. Alsamixer does some fancy console graphics and didn't work for me through the serial console. I had to log in from an xterm via ethernet to be able to actually control alsamixer. You need to be logged in as user meego (not root) and start alsamixer. You'll see one single volume bar. This is the pulseaudio setting. You need to unmute this (press 'M') if it's muted (indicated by 'MM' at the bars bottom. The 'MM' should become green '00'. Also increase volume to max using cursor up if necessary, Then hit 'F6' and switch to the omap3beagle setup. This is the hardware config. You need to unmute and increase the volume of at least the following entries: DAC1 Analog DAC1 Digital Course DAC1 Digital Fine Headset HeadsetL Mixer AudioL1 HeadsetR Mixer AudioR1 Entering the following command should now give you an audible output on the headphone jack: aplay /usr/share/sounds/alsa/Rear_Center.wav If you don't hear anything you'll likely have to adjust the omap3beagle settings in alsamixer. Fortunately these settings are automatically saved and restored at system reboot. You thus only need to adjust these once. ---------- ------------ ------------- ------------ --------- Niels http://nielsmayer.com PS: Is http://www.igep-platform.com/ the recommended way of getting such a device? Are there any cheap Taiwanese/Chinese MIPS-based touchscreen knockoffs I should know about because "igep-platform" looks quite fancy.
