My HP Envy 13 is using a HD Realtek sound device. In Linux, it's using the ALC295 driver.



Sound works out of the box, but didn't sound as full as it had on Windows. Here's aplay -l

Seems fairly standard, except that 'speaker-test -c 6' (which plays the sound on Front Left, Center, Front Right, Rear Right, Rear Left, and LFE in that order) sounds like it's playing sound through 5 different speakers. LFE has no sound, Rear Right and Rear Left are much softer.



Marketting material from this laptop (and my ears) say that there's quad speakers in it. How can I get multi-channel audio playing from this laptop via alsa or pulseaudio?

  • Yeah I know about pulseaudio profiles but in this case there's only Analog Stereo Out and a bunch of HDMI options. Pulseaudio's surround sound is fairly restricted and alsa-reliant, as far as I can tell, hence my question focusing on Alsa.

How many registers does an x86_64 CPU actually have?

Image
Clash Royale CLAN TAG #URR8PPP up vote 2 down vote favorite I am currently learning reverse engineering and am studying the flags register. I had in my mind that rflags was just another name for one of the 16 general purpose registers, for example rax or rbx . But it looks like rflags is actually an additional register. So that makes 17 registers in total... how many more could there be? I have spent at least an hour on this and found numerous different answers. The best answer so far is this, which says that there are 40 registers in total. 16 General Purpose Registers 2 Status Registers 6 Code Segment Registers 16 SSE Registers 8 FPU/MMX Registers But if I add that up, I get 48. Could anybody provide an official answer on how many registers an x86_64 CPU has (e.g. an Intel i7). Additionally, I have seen references to 'hardware' and 'architectural' registers. What are those registers and how many are there? register x86-64 share | improve this...
