Then connect an audio cable from the computer to the monitor. That's the simplest solution for your situation.

It is highlighetd on the box of my graphic card that it card has 1.3a version HDMI connector. As per table found https://en.wikipedia.org/wiki/HDMI HDMI ver 1.3a can support 2560x1440 resolution.
Will I be so unlucky that despite the built in HDMI 1.3a version connector resolution maximum of my HD4000 series card is only 1920x1080 on HDMI because of some hardware limitations, irrespective the card is able to send out above full HD resolutions on DVI?

It's not technically impossible. The hardware can probably do it, but the driver doesn't allow it, and I haven't found a way to patch it for 4000-series GPUs. Back then, nothing used more than 1920x1080 @ 60 Hz with HDMI. AMD didn't officially support anything higher with HDMI until the 7000-series GPUs. Dual-link DVI has two links, so it can carry twice as much data.

Or an adapter like this
Do you think it is worth to try?

There is no such thing as dual-link DVI to HDMI. HDMI is single-link. All that adapter will do is make the DVI port act like an HDMI port, so it will have the same limitations.

Like I said, the patch is meant for 5000-series and newer GPUs. It can't get around HDMI limits for 4000-series GPUs.
