The device used for hardware audio device is a Creative Labs Sound Blaster Live! 24 bit USB device using S/PDIF digital output to the amplifier. The device setup in the MythTV general settings for the audio output device is: ALSA:iec958:CARD=EXTERNAL,DEV=0. When watching recordings, the sound is perfect. Using the OSS device for the music audio output device (/dev/dsp1) also works perfectly. Disabling the upmixing in the music general settings makes the music playback better, but the stuttering is still very much evident. I have attached the sections from the frontend log that shows the audio setup for both watching recordings and for listening to music. Other than the sampling rate being different, there must be something else done differently in setting up the audio between watching recordings and listening to music that perhaps only effects the usb_snd driver. Pulseaudio is disabled on this system. OS: Ubuntu desktop 10.04 Please attach all output as a file in bug reports.
