Title: No sound during high sample rates audio playback on MacBook Pro 7.1 Status in “alsa-driver” package in Ubuntu: Confirmed Bug description: Sample rates higher than 48kHz produce no sound in my setup both in pure alsa mode and pulseaudio (with default-sample-rate: 192000 or 96000 in /etc/pulse/daemon.conf) modes. Following strings shows that audio hardware is set to this mode with no alsa resampling or something similar. aplay -D plughw:CARD=NVidia,DEV=0 high_def_audio.wav cat /proc/asound/NVidia/pcm0p/sub0$/hw_params access: MMAP_INTERLEAVED format: S32_LE subformat: STD channels: 2 rate: 192000 (192000/1) period_size: 4096 buffer_size: 8192 P.S. Sorry for using non stock kernel this is due to https://bugs.launchpad.net/ubuntu/+source/v86d/+bug/1080530 (build from #22 with single patch applied) but problem can be reprodused in "pure" setup.
