JU Argh, yet another implementation strategy from a vendor. Too bad, but remember, this is why we use ALSA now instead of OSS. :-) > this leads to a rather awkward result in alsamixer where there are 5 > volume controls called "Master": > > < Master > Master Master Master Master > > IMHO, it would be more desirable for them to say: > > < Master > Front C/LFE Surround Rear Surr Yes. Alsamixer chooses to display an eight-channel control this way. This can be considered a bug in alsamixer. JU It *could*, but that's probably an impractical perspective. zillions of other drivers present this data in the way that amixer, alsamixer and many other mixers expect.
