But if I mute and unmute (either through my application or using alsamixer), the sound playback resumes on both left and right speakers. This only happens on a particular system too (out of 5 systems). But I know it is my issue because mplayer or smplayer works fine. I believe I am setting the correct HW params (ie. 2 channels), etc. Any ideas? Thanks! ^ permalink raw reply [flat|nested] 12+ messages in thread

The case of envy24* drivers, the problem is the initialization of the registers via I2C/SPI. But, in the case of HD-audio, this can't be the case. I fixed a similar case with VIA HD-audio codecs by limiting the supported PCM formats to 16. The 24 bit format was buggy on them. Possibly a similar situation.
