can we use hdmi and rca at the same time on a LED tv?
basically hdmi for video, but sound using my external speaker connecting to rca?
Mmm... I want to understand more clearly on what you want here. Its confusing without enough info.
Ok... I will make assumptions here so do correct me if its not what you want.
Assumption 1If you want to use RCA audio out from TV to your speakers, then not possible when RCA Analog Stereo out is not available on TVs. Normally there are TVs (not all) which do have Optical Audio out or (maybe) Co-axial out which allow connection to an AVR. Connecting Opt Out in this way allows a "smart TV" with internet browser or online apps (Netflix) to output sound to the AVR instead of only the TV speakers.
Assumption 2Mmm... bluray players now already do not have RCA analog stereo out to connect to any AVR or active speakers.
When you say "using my external speaker connecting to RCA"... you meant your speakers are "Active" ones which have its internal amp and can accept input directly from source players.
Assuming your "old" player have analog RCA stereo out, you want to connect...
"bluray or DVD player" HDMI >> directly to your TV.
Same "bluray or DVD player" RCA out connect to "active" external speakers.
Yes, you can when active speakers are used. No, when passive speakers are used, that need an AVR or Pre+Power Amp.
If correct, I assume that you do not have an AVR. So you want to use your player to use your external speakers instead of sound from your TV. I guess you set your player to decode audio as "PCM" out (not bitstream). Mmm... you want better sound from your speakers instead of your TV when playing DVD, bluray, etc.
Assumption 3You have an older Astro Decoder which have analog RCA Stereo Out.
You don't want to use any AVR. You just connect Astro HDMI directly to TV and then Astro RCA out to your active external speakers. The Astro "Digital Audio" settings must use "Stereo (Analogue and Digital). So you want better sound for Astro by using your external speakers, not from TV speakers.
Yes, you can. Obviously no 5.1 surround audio for 2 external speakers.

If none of the above, then please let me know in more detail such as...
(1) what player or source is used?
(2) player connect to what?
(3) is there any TV out connection?
(4) active or passive speakers?
(5) is there any AVR used?
(6) what is the purpose you want to use HDMI for video and RCA for audio?
If possible, it will help by drawing a simple diagram showing all the hardware connections that you want.
